Requirement for Router 3: 1. Redistribute routes learned from EIGRP in to
OSPF. 2. Redistribute OSPF routes in to BGP.
Problem: R3 is receiving routes through EIGRP that are being redistributed
into OSPF, but aren't making it into the BGP table-- sample routes are
212.12.1.0, 212.12.7.0, 212.12.8.0, ... & 212.12.12.0. Is there anything
special one should consider when performing multiple redistribution such as
this on the same router?
Relevant configs and show commands below....
