Version 6.8 11 Mediant MSBR
Configuration Guide 1. Introduction
1 Introduction
As an all-in-one product family, the MSBR provides a variety of data services. As a rule,
data services of any-size organization are based on IP networking as a standard, as IPv4
(and in the future, IPv6) are the official and standard suits of data network protocols.
This document deals with the IP data functionality of the MSBR and addresses the purpose
of listing and explaining the kinds and nature of the IP protocols supported by the MSBR,
explaining their most common uses and functionality, how to configure and implement
them in an existing network, and demonstrating the most common and real-life-like
scenarios and best practices in which those protocols can and should be used. In addition,
a list of available commands and options for each protocol is described.
The examples in this document include topology, configuration methods and sample output
and verifying commands to better understand the way they operate.
All mentioned protocols and technologies can be used in a more complex and advanced
configuration than some of those demonstrated in this document; however, the main goal is
to demonstrate common and well-tested implementations.

Version 6.8 13 Mediant MSBR
Configuration Guide 2. IPv4
2 IPv4
IPv4 is the common and most widespread version of the Internet Protocol which is
responsible for routing traffic on the internet and private networks. IPv4 also defines the
structure and rules of IP addressing for network devices and nodes.
MSBR maintains a routing table which lists the IP addresses familiar to the device and how
to reach them in terms of next-hop. Information stored in the routing table is received from
different sources, such as local physical and logical interfaces, static routes configured by
the network administrator, and dynamic routing protocols. All of the listed items are seen as
different routing domains.
IP addresses on the MSBR are configured on interfaces, and usually are accompanied by
the subnet mask, which is used for the subnet calculation.
Each Layer-3 interface can be assigned one primary IP address, and several secondary IP
addresses. Secondary IP addresses are typically used to provide connectivity to several
subnets through a single interface, facilitating network transitions and multi-homing.
2.1 Example of Primary and Secondary IP Address
Configuration
The following is an example of primary and secondary IP address configuration.
2.1.1 Configuration
MSBR# configure data
MSBR(conf-data)# interface VLAN 1
MSBR(conf-if-VLAN 1)# ip address 192.169.12.1 255.255.255.0
MSBR(conf-if-VLAN 1)# ip address 192.169.0.1 255.255.255.0
secondary
MSBR(conf-if-VLAN 1)# no shutdown
2.1.2 Output
MSBR# show data int vlan 1
VLAN 1 is Connected.
Description: LAN switch VLAN 1

Configuration Guide 14 Document #: LTRT-31657
2.2 Interface VLAN – Link State Monitor
MSBR handles physical and logical interfaces. While the state of a physical interface is
determined by whether its connected to the power (plugged in or not), logical interfaces,
such as interface VLAN, can remain in UP state even if ports associated with them are
disconnected. To prevent such a scenario, it is possible to enable a link-state monitor,
which probes the state of VLAN-associated interfaces, and brings down VLAN interfaces if
ports associated with them are disconnected.
2.2.1 Configuration
Command Description
MSBR# configure data
Enters the data configuration menu.
(config-data)# interface vlan
vlan
Enters the interface vlan configuration mode.
(conf-if-Vlan
num
)# link-state
monitor
Enables the link-state monitor.

Version 6.8 15 Mediant MSBR
Configuration Guide 3. ICMP
3 ICMP
Internet Control Message Protocol (ICMP) is one of the main protocols in the IP suite and
in general, is used by network equipment to obtain information or notify about data delivery
problems, for example, in case a specific service is unavailable or a specific network or
host is unreachable.
The most common and known usages of ICMP are the ping and traceroute
commands, using ICMP messages to test IP reachability to an IP address on the internet,
and to verify the IP “hops” a packet travels on its way to the destination, respectively.
The ICMP protocol “runs” over UDP and is defined in RFC 792.
3.1 ping
The ping tests IP reachability to a desired destination. If the destination is reachable, there
will be the same amount of echo requests and replies.
Command structure:
ping <IP address / host> options
where the options are:

repeat - amount of ICMP requests to send.

size - size of the of the ICMP packet in bytes.

source – source from where to send the packets

summarized - display summarized results (! - successful reply, .U - No reply, timeout
and Unreachable)

source [data voip]- interface to use as source address for the ICMP requests. Voip or
data interfaces can be used. “Source voip” – allows you to select the source interface
as name or as VLAN number. “Source data – allows you to select any interface as
source for ping. The pings are sent from this interface. “Source data source-address”
allows you to ping from IP of any address while the next hop calculated using the
routing table. “Source data vrf” allows you to ping from any configured VRF.
Typical output:
MSBR# ping 192.168.0.3
Reply from 192.168.0.3: time=1 ms
Reply from 192.168.0.3: time=1 ms
Reply from 192.168.0.3: time=1 ms
Reply from 192.168.0.3: time=1 ms
4 packets transmitted, 4 packets received
Round-trip min/avg/max = 1/1/1 ms

IP Networking Configuration
Configuration Guide 16 Document #: LTRT-31657
3.2 Traceroute
The ping command informs you if the destination is reachable or not. Traceroute can be
used to discover the path that packets travel to the remote destination.
Command structure:
traceroute <IP Address / host> [vrf | source-address]
Typical output:
MSBR# traceroute 8.8.8.8
1 192.168.0.1 (192.168.0.3) 1.169 ms * 7.346 ms
2100.100.100.2 (100.100.100.2) 1.169 ms * 7.346 ms
.

Traceroute: Destination reached

Configuration Guide 4. VRRP
4 VRRP
VRRP provides for automatic assignment of available routers to participating hosts. This
increases the availability and reliability of routing paths via automatic default gateway
selections on a LAN.
The protocol achieves this by creating virtual routers, comprised of master and backup
routers. VRRP routers use multicast to notify its presence in the LAN (never forwarding
outside of the LAN).
VRRP is based on RFC 2338 and RFC 3768.
4.1 Feature Key
Advanced routing feature key must be enabled.

4.3 VRRP Example
In the example below, there are two VRRP routers – one with IP 10.100.10.2 and one with
10.100.10.3. They use a common virtual IP address 10.100.10.1, where one is the Master
and the other is the Backup. In the example, we will use VRID 1 over VLAN 1.
Figure 4-1: VRRP Example
The Master will be the MSBR with the higher priority. For example:

Master configuration:
Mediant 800B# configure data
Mediant 800B(config-data)# interface vlan 1
Mediant 800B(conf-if-VLAN 1)# vrrp 1 ip 10.100.10.1
Mediant 800B(conf-if-VLAN 1)# vrrp 1 priority 200
Mediant 800B(conf-if-VLAN 1)# exit
Mediant 800B(config-data)

Backup configuration:
Mediant 800B# configure data
Mediant 800B(config-data)# interface vlan 1
Mediant 800B(conf-if-VLAN 1)# vrrp 1 ip 10.100.10.1
Mediant 800B(conf-if-VLAN 1)# vrrp 1 priority 100
Mediant 800B(conf-if-VLAN 1)# exit
Mediant 800B(config-data)

The following is an example of the show run command for two MSBRs:

Master:
M500 *# show run
