eigrp routes after hsrp implementation

Trying to figure this out,

3640 primary

2621 secondary

both connected to a 4003 switch with dot1q vlans

and a 2924xl switch on the other interface which also connects to a 2621

/------ 3640 ----\

4003 (vlans) 2924---------2621---4003

\------ -2621-----/

which is indicating some odd eigrp behavior

hsrp stats from primary router

....

FastEthernet0/1 - Group 4

State is Active

1 state change, last state change 2d07h

Virtual IP address is 63.117.77.130

Active virtual MAC address is 0000.0c07.ac04

Local virtual MAC address is 0000.0c07.ac04 (default)

Hello time 5 sec, hold time 15 sec

Next hello sent in 3.040 secs

Preemption enabled, min delay 0 sec, sync delay 0 sec

Active router is local

Standby router is 192.168.150.42, priority 100 (expires in 13.000 sec)

Priority 120 (configured 120)

D 192.168.3.0/24 [90/30720] via 192.168.150.41, 2d07h, FastEthernet0/1

why are both the primary routers showing up on the far routers' ip table?

both hsrp and eigrp indicate 2d+ states

Re: eigrp routes after hsrp implementation

Clarification and summary

the last part should read:

eigrp routes from far router:

D 192.168.1.0/24 [90/30720] via 192.168.150.42, 2d07h, FastEthernet0/1 [90/30720] via 192.168.150.41, 2d07h, FastEthernet0/1

D 192.168.2.0/24 [90/30720] via 192.168.150.42, 2d07h, FastEthernet0/1

[90/30720] via 192.168.150.41, 2d07h, FastEthernet0/1

why are both the primary AND SECONDARY routers showing up on the far routers' ip table?

both hsrp and eigrp indicate 2d+ states

Re: eigrp routes after hsrp implementation

It should be like this since both routers is propogating the routes.

It looks like you have had a change in your network at the spesific time that influenced both the eigrp and hsrp. As you know, eigrp and hsrp is separate processes.

Re: eigrp routes after hsrp implementation

So what you are essentially saying is that eigrp is conflicting with hsrp and keeping the 2nd router active, as I indicated earlier.

There is a way to do this, it is just a matter of tweaking the switches' stp/trunk/port values...except I am coming up dry on the solution..

eigrp has been running fine for some time now. I added hsrp to the mix, but it is conflicting with eigrp and causing a loop.

the 2 routers are plugged into a 4003. At first, I set the trunks to dot1q on, which works fine, but have read references on cisco.com to set the trunks to desirable. I tried that, but the port leaves trunk state after a few seconds.

2002 Jul 31 04:42:06 %DTP-5-NONTRUNKPORTON:Port 3/1 has become non-trunk

2002 Jul 31 04:42:06 %SYS-4-P2_WARN: 1/Tag 10 on packet from 00:03:e3:53:a9:c1 port 3/1, but port's native vlan is 1.

Re: eigrp routes after hsrp implementation

Ok, after sorting thru the overwhelming response and doing some trial and error. I changed 2 routes to static and that took care of the routing loop.

the secondary router was supposed to be "asleep", but it didn't listen. I shall rename it after my daughter, who doesn't doesn't go to sleep when she is supposed to either.
