I know this topic has been covered many times, can someone please check if I
have them right?
Thanks.
A. OSPF and IGRP are in the same major network 172.16.x.x/16
A.1. 2.1/24--->ospf<-1.1/24---1.2/24-->igrp:
action: no need to do anything
A.2. 2.1/28--->ospf<-1.1/24---1.2/24-->igrp:
action: ospf summarize to 2.0/24
A.3. 2.1/28--->ospf<-1.1/28---1.2/28-->igrp:
action: need 3.1/24, 3.2/24 secondary address at ospf-igrp link and
ospf summarize to 2.0/24
A.4. 172.16.x.x/15->ospf<-1.1/24--1.1/24-->igrp:
action: ???
B. OSPF in 172.16.x.x/16, IGRP in 192.168.1.x/24, inter-network in
192.168.1.x:
B.1. 2.1/24->ospf<-1.1/24---1.2/24->igrp:
action: do nothing
B.2. 2.1/28->ospf<-1.1/24---1.2/24->igrp:
action: ospf summarize to 2.0/24
B.3. 2.1/28->ospf<-1.1/28---1.2/28->igrp:
action: need 192.168.3.1/24 and 192.168.3.2 secondary addresses, ospf
summarize to 2.0/24 network.
B.4. 172.16.0.0/15->ospf<-1.1/24--1.2/24->igrp:
action: ip default-network 2.0/24 in ospf
or reverse summaization to cover all 172.16.x.0/16 involved
