I am trying to form an EBGP adjaceny and they are not peering R6 and R8. Please advise
They are directly connected
Configuration below:
R6#sh run | s bgp
router bgp 3
no synchronization
bgp log-neighbor-changes
neighbor 9.9.9.9 remote-as 89
neighbor 9.9.9.9 update-source Loopback1
neighbor 9.9.9.9 soft-reconfiguration inbound
no auto-summary
R6#sh ip bgp summ
BGP router identifier 6.6.6.6, local AS number 3
BGP table version is 2, main routing table version 2
1 network entries using 132 bytes of memory
1 path entries using 52 bytes of memory
2/1 BGP path/bestpath attribute entries using 336 bytes of memory
0 BGP route-map cache entries using 0 bytes of memory
0 BGP filter-list cache entries using 0 bytes of memory
Bitfield cache entries: current 1 (at peak 1) using 32 bytes of memory
BGP using 552 total bytes of memory
BGP activity 1/0 prefixes, 1/0 paths, scan interval 60 secs
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd
9.9.9.9 4 89 0 0 0 0 0 never Idle
R6#ping 9.9.9.9
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 9.9.9.9, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/28/32 ms
R8#sh run | s bgp
router bgp 89
no synchronization
bgp log-neighbor-changes
neighbor 6.6.6.6 remote-as 3
neighbor 6.6.6.6 update-source Loopback1

Only you need this
Neighbor x.x.x.x ebgp multihop
You use LO not direct connect IP so ebgp is far than one ttl that why ebgp failed
