Avaya 555-245-600 manual Service Provider Access Links, BGP on the Engine Module

Configuring CNA

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.
