Hello, all.
I'm testing the result of this command in EIGRP. Based on what I've read
in the past, EIGRP AUTOMATICALLY propagates the candidate default
network into the EIGRP domain as the default candidate if these two
requirements are met:
1. The "default-network" must be on a MAJOR CLASSFUL boundary.
2. The "default-network" must be in the routing table as
External-EIGRP.
But I'm not seeing the described behavior. Here's my scenario.
2511---rip---2514---EIGRP---2516---EIGRP---mc3810b
2514 is redistributing RIP into EIGRP, and the network in question is
192.168.10.0 between 2511 and 2514.
2516 is configured with "ip default-network 192.168.10.0" and installs
this as its Gateway of Last Resort. But it's neighbor mc3810b
does not treat this network as a Candidate Default.
The relevant configurations and route tables are shown below. If anyone
has any idea what's not right, please let me know. Thanks.
