Configuring An Ibgp Multi-Hop Session Between 2 Avaya Secure Routers - Avaya 1000 Series Configuration Manual

Configuring an IBGP Multi-Hop Session between 2 Avaya Secure
Routers
CONFIGURATION OF Avaya1:
interface bundle ToAvaya2
link t1 4
encapsulation ppp
ip address 40.40.40.1 255.255.255.0
exit
interface loopback 1
ip address 60.60.60.1 255.255.255.255
exit
ip route 60.60.60.2 255.255.255.255 40.40.40.2 1
router bgp 100
neighbor 60.60.60.2 100
exit
exit
CONFIGURATION OF Avaya2:
interface bundle ToAvaya1
link t1 4
encapsulation ppp
ip address 40.40.40.2 255.255.255.0
exit
interface loopback 1
p address 60.60.60.2 255.255.255.255
exit
ip route 60.60.60.1 255.255.255.255 40.40.40.2 1
router bgp 100
neighbor 60.60.60.1 100
exit
Note in the above configuration we have added an ip route command to reach the other side
loopback interface. We need to have a route to reach the bgp peer address, either through a
static route or through any other protocol like rip / ospf.
Now we can ping the peer address 60.60.60.1 from Avaya2, but the "show ip bgp summary"
still shows the connection to be in Active state.
Reachability to the peer address is achieved, but the session is still in an Active state. The
BGP Session is not established because there is one thing that is missing still. When BGP
Initiates a connection with another peer, it would always use its outgoing interface as its source
address. In this case Avaya2 would use 40.40.40.2 and Avaya1 would use 40.40.40.1. But
