I'm having problems with the above.
I have all routers configured except burke (I did initially but regressed
rying to fix this!).
When I issue sh Ip bgp, I see all EIGRP routes twice (makes sense - two
paths), with the best selected on all routers with exception of Sugarbush -
Sugarbush learns them both for a second, then loses the one through Diamond.
An example of show ip bgp 192.168.192.80 before and after.
Anybody got any ideas why Sugarbush loses the path through Diamond? Or tips
on my config?
Thanks in advance.
