Hi all,
I've been doing some debugging of EIGRP packets and noticed that Hello
packets are sent to the Loopback interface when configured:
Feb 2 13:47:29 pst: EIGRP: Sending HELLO on Loopback0
Feb 2 13:47:29 pst: AS XXXX, Flags 0x0, Seq 0/0 idbQ 0/0 iidbQ un/rely
0/0
Feb 2 13:47:29 pst: EIGRP: Received HELLO on Loopback0 nbr XXX.XXX.XXX.XXX
Feb 2 13:47:29 pst: AS XXXX, Flags 0x0, Seq 0/0 idbQ 0/0
Feb 2 13:47:29 pst: EIGRP: Packet from ourselves ignored
I've looked in Pepelnjak's book to see if this is needed and I don't see it
mentioned anywhere. Is this not just wasting CPU cycles on a meaningless
endeavor? Is this required in order for EIGRP to function properly? If I
could I'd like to put in a passive-interface for the Loopback. Enjoy the
weekend.
Jim
