Configuring an EBGP Multi-Hop Session between an Avaya Router
and a 3rd Party Router
CONFIGURATION OF Avaya1:
interface
link t1 4
encapsulation ppp
ip address 30.30.30.1 255.255.255.0
exit
interface
ip address 60.60.60.2 32
exit
ip route 60.60.60.3 32 30.30.30.3 1
conf term
router bgp 100
neighbor 60.60.60.3 200
ebgp_multihop
update_source 60.60.60.1
On an IBGP Multihop session we need to take care of only the update_source for getting the
BGP to an Established state, but in case of EBGP neighbors we have to specify the session
to be EBGP_MULTIHOP in their neighbor configuration itself.
