Router 8 and Router 6 are running EIGRP. Router 6 has only the Serial
interface connecting to r8 advertized in EIGRP
Router 6 is redisributing BGP into EIGRP. All the BGP routes from as100
appear in r8 table
The 62.8.1.0 network that is directly connected to r6 does not ?

If netB is learned from an IBGP peer, it can not be redistributed into IGP
for loop avoidance.But if you insist on redistributing it you can use the
command "redistribute bgp redistribute-internal". Probably the other BGP
routes were learned from an EBGP peer, so you can see them in your EIGRP
table.

Subject: Redistribution Question
Router A has BGP and EIGRP running on it. Net B is directly connected and is
in the BGP table. Net B is not part of the EIGRP process. I am
redistributing BGP into EIGRP. Net B does not appear in the EIGRP next hop
router but all the other BGP routes do ?
Is there a gotcha revolving around redistribution of networks that are
directly connected ?
