I re-configured this in the lab and like Ralph is mentioning, it's
working. Error was on my side.
Does anyone have a summary of the issues/workarounds of peering to
secondary addresses with various routing protocols? I believe the fix is by
using a common bridge-group and applying an IP address to the BVI interface,
but I'm not 100% on this.
Sincerely,
Dennis J. Hartmann

Dennis,
Here is a sample config, when I try to advertise a secondary address into
eigrp using network statements.
R3:
interface Loopback2
ip address 148.6.11.11 255.255.255.0 secondary ip address 150.6.33.33
255.255.255.0 !
R5: (from sh ip route)
D 148.6.11.0/24 [90/2297856] via 148.6.35.3, 00:05:31, Serial0/0
R5#PING 148.6.11.11
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 148.6.11.11, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 56/57/60 ms
I observed that on loopbacks and ethernet interfaces eigrp is able to
advertise secondary addresses fine, but on NBMA interfaces, you have to
disable split-horizon to advertise the secondary address.
Regards
Ralph

Subject: EIGRP and secondary IP Addresses
My understanding is that EIGRP can not have a neighbor relationship
and/or advertise a secondary IP Address on an interface. I tested this by
trying to advertise a secondary IP Address on a Loopback interface trying
both the network command and trying to do a redistribute connected with a
route-map that matched on the Loopback interface only. Neither method
worked. In this type of scenario, I believe one would be forced into using
the auto-summary option in the EIGRP routing protocol process OR use the ip
summary-address command on an interface. Opinons and/or comments
welcome.....
Sincerely,
