BGP Neighbours not forming

[ThomasCampbell64]

I have to iBGP peers that are not forming. I can't seem to find why.... I have added IGP underlay but they can't reach the loopback addresses I have set the neighbors too. They can ping each other but unable to ping their loopback addresses.

XR1:

router bgp 65001
bgp confederation peers
65002
!
bgp confederation identifier 100
bgp router-id 10.1.1.1
address-family ipv4 unicast
!
neighbor 10.2.2.2
remote-as 65001
update-source Loopback0
address-family ipv4 unicast

XR2:

router bgp 65001
bgp confederation identifier 100
bgp router-id 10.2.2.2
address-family ipv4 unicast
!
neighbor 10.1.1.1
remote-as 65001
update-source Loopback1
address-family ipv4 unicast
!

ebgp-multihop [ ttl-value ] <<- this need in both router **

also make sure that LO is reachable in both routers

The is an iBGP lab. I am used to having all the routers loopbacks in the routing table so not sure if its a bug running on EVE-NG

you need to reach IP of loopback x from IP of loopback y; for testing, use ping x source y 

add static routes or advertise them into ospf -if ping fail;
