Configuring CNA
Issue 6 January 2008 361
Service Provider Access Links
Each service provider that is to be managed or monitored by Avaya CNA needs a link object
defined. From config mode, enter engine configuration mode:
module engine
To associate a service provider with a link name, create the links using the link command.
link provider_1
provider-as 10 172.30.100.33
end
link provider_2
provider-as 20 172.29.100.33
end
link provider_3
provider-as 30 172.28.100.1
end
The name provider_1 will be used in the output of various CLI commands and web page
reports. The provider-as command associates the provider_1 link with both the Autonomous
System (AS) number of the corresponding service provider; and the IP address of the provider
edge the enterprise’s edge router is peering with.
BGP on the Engine Module
While still in config-engine mode, enter the bgp command, with the enterprise network’s AS
number as the as-num argument:
bgp 65002
neighbor 172.16.6.1 link provider_1
neighbor 172.16.6.1 remote-as 65002
neighbor 172.16.6.2 link provider_2
neighbor 172.16.6.2 link provider_3
neighbor 172.16.6.2 remote-as 65002
end
A neighbor link command needs to be entered once for each of the links. The command takes
address and name arguments, in the following form: The address argument is the IP address of
an interface on the edge router that connects the enterprise network to the service provider
identified by the name argument.
Also, in order to achieve IBGP peering, the router IP addresses need to be associated with the
enterprise’s AS numbers, using the neighbor remote-as command.
