I'am playing with secoundary adressen an IGRP.
That's my interface configuration:
R3#sh run int ser 0
Building configuration...
Current configuration:
!
interface Serial0
bandwidth 1984
ip address 10.1.30.2 255.255.255.0 secondary
ip address 10.1.10.2 255.255.255.252
no ip directed-broadcast
encapsulation frame-relay
no keepalive
frame-relay map ip 10.1.10.2 100 broadcast
frame-relay map ip 10.1.30.2 100 broadcast
frame-relay interface-dlci 100
When I look to the FIB on the router I see this:
I 10.1.30.0/30 [100/9040] via 10.1.30.1, 00:00:03, Serial0
C 10.1.30.0/24 is directly connected, Serial0
Why have I two routing entries in the table. Because of the different
subnetmasks on the same interface ?
I seems that IGRP takes also the subnetmask from the primary interface for
the secoundary interface and probagate it to all IGRP speakers.
Is this a normal issue, or only IGRP related ?
