Hi,there:
I'm studying the section of <neighbor doorback> in Halabi's book,
But unfortunately, I never get pass.
Please watch the topology attached in this mail, The 3640-1,2610,
2501-2 router run bgp protocol,but ospf run between 3640-1 and
3640-2.
The question is if I use clear ip bgp * command, the ospf route
192.68.5.0 255.255.255.0 192.68.6.2 will appear in 3640-1's routing
table,but after BGP peer established,this route was replaced with
BGP route 192.68.5.0 255.255.255.0 172.16.20.2.
I know the reason is the distance,but the fact is I have set the
<network 192.68.5.0 backdoor> command in 3640-1!
the BGP route 192.68.5.0 255.255.255.0 172.16.20.2's distance should
change from 20 to 200 and that ospf's route should stay in 3640-1's
routing table,it cann't be replaced by BGP's route again! SO,I cann't
understand completely.
Another question:
When I use <clear ip bgp *> command, then <sh ip route ospf>, I can
find the route 192.68.5.0 255.255.255.0 192.68.6.2 appeared,but the BGP
esatblished,the route then disappeared from the output of the <sh ip route ospf>.
What's happen ?
Thank in advance...
