Hi Sabrina,
Thanks for the response. Incase of EBGP,a router generates a packet with a TTL of 1 and it send it to the neighbor.Even if the peering is is with the loopback,the neighbor should be receiving the packet and then it should drop.In this case,'debug ip packet detail' on the neighbor should capture the received packet.right?
If for EBGP, if the packet generated by the router with TTL of 1 is not sent to the neighbor itself,then even if the peering is between the directly connected interfaces,neighborship would not be formed.Please correct me if I am wrong.
thanks
Mani

let's put it in this way...a router will never forward a packet that has been received with TTL equal to 0 or 1

Subject: TTL
GS,
Can someone let me know where does the TTL get decremented? Is it on the ingress of the receiving router or on the egress of the sending router.
When I configure EBGP between two routers with their loopback IP addresses and enable 'debug ip packet',I am not seeing any packet coming in.So I assume that the TTL is decremented on the egress interface of the sending router.Can someone confirm.
