Hello,
I have this strange behavior where an ospf process would not summarize externally learned routes... I am getting a bunch of rip routes redistr'ed into my ospf process. R6 is supposed to summarize those into 77.77.0.0/16, but it does not originate that summary... If you notice under protocols printout, "Address Summarization:" is empty... And the immediate neighbors of R6 dont get that summary.
Wonder if someone can spot whats wrong with this:
R6#sh ip ospf summary-address
OSPF Process 1, Summary-address
77.77.0.0/255.255.0.0 Metric -1, Type 0, Tag 0
R6#sh ip route | i E2
E1 - OSPF external type 1, E2 - OSPF external type 2
O E2 77.77.1.0/24 [110/20] via 77.77.36.7, 00:10:21, Ethernet0/0
O E2 77.77.13.0/24 [110/20] via 77.77.36.7, 00:10:21, Ethernet0/0
O E2 150.1.77.0 [110/20] via 77.77.36.7, 00:10:21, Ethernet0/0
R6#sh ip protocols
