Hello,
I managed to get it up. Seems like this peering needed authentication to
come up, however this was not mentioned in the task itself. The peering came
up as soon as I configured password for the neighbor :-)
Thanks,
Ajay

Subject: Cannot Get BGP peering to come up!!
Hello,
I am kind of stuck while trying to get the BGP peering up between R2

troubleshoot this
