Hey All:
 
(PS: My last name is Todd, First name is Douglas)
 
I have used the ttl-security feature in place of the ebgp-multihop. My routes
are inaccessible, regardless of the hop count used.
 
Process:
 
1) I do a trace from source to destination
2) 4 hops are seen
3) add 1 hop to the 4
4) I have 5 hops now.
 
nei a.b.c.d ttl-security hop 4
 
I have tried 5 hops, 6 hops 7 hops. The neighbor comes up, route are
inaccessible. If I use multihop, routes are fine.
 
Some ideas?
 
Thanks.
 
Douglas
