Hi,
This may sound like a stupid question, but I have been studying now for 5
days solid so my brain may be fried..
I seem to have lost grip on BGP and how it interacts with IGP.
I have a set of routes in by BGP table , for which the next hop is known and
pingable by my IGP on the same router. When I try and ping the BGP routes I
get timeouts from an intermediate IGP router because it doesn't know the
route to my BGP destination. It does however know the route to the BGP next
hop.
If I put a static default route out to my BGP Backbone router in this
intermediate IGP router I get a ping, but this isn't correct or practical..
Have tried all the usual next-hop-self tricks but this just changes the BGP
next hop to another IGP address which is also accessible through my IGP and
I get the same timeout.
Have also advertised my LO0 networks in BGP and run an extended ping from my
LO0 as source, makes no difference.
I am definitely missing something here.
Where am I going wrong people!
Thanks in advance
Kriz
