Elmer/Cebuano,
On my core router:
D 192.168.0.0/22 [90/2169856] via 116.16.37.2
On my ABR I have configured:
ip summary-add eigrp 100 192.168.0.0 255.255.252.0 5
A# To me it DOES seems that the core router learns the
summarization as a InternalEIGRP route with AD of 90.
This is testing with 12.2(12.5)T, I can also test with
12.2(10b) if you like.
Q) Anybody else know why? According to AD charts
summarized EIGRP routes = 5
Cheers,
Sage
