port based vlan on 8600 switches dual homed.

[steven0000]

G'day all,

I am very new to nortel gear but have been thrown in the deep end. I have 2 8600s using vrrp. I need to create a new vlan for a new location that is running over fiber. I am running into problems with the routring. So far I have created the VLAN (as best I could) added the port I want to use. I have learnt on the fly about the vrrp association to my vlan and I have created that also, but both vrrp entries on the different switches are sitting in 'initiaze' states. and my packets are not being routed past the Gateway.
My questions are how do I get the vrrp entries to go master/backup? The switches learn the routes automatically fine, but what protocol are they using to find the routes?

again I am a complete newbie to nortel, but experienced in cisco and 3com. Any and all assistance will be greatly appreaciated.

Thanks in advance.

Steven

It sounds like the 8600s can't talk to each other. Can you describe how you have the three switches connected? Whenever I have configured VRRP in the past as soon as I had both switches online and configured they recognized each other and came up backup and master.

Find below the relevant statements used in our campus LAN.

Switch 1
vlan 1 ip create 172.23.2.4/255.255.224.0 mac_offset 0
vlan 1 ip vrrp 10 address 172.23.1.10
vlan 1 ip vrrp 10 backup-master enable
vlan 1 ip vrrp 10 holddown-timer 60
vlan 1 ip vrrp 10 enable

vlan 4 ip create 172.23.227.3/255.255.255.0 mac_offset 1
vlan 4 ip vrrp 20 address 172.23.227.1
vlan 4 ip vrrp 20 backup-master enable
vlan 4 ip vrrp 20 holddown-timer 60
vlan 4 ip vrrp 20 enable

Switch 2

vlan 1 ip create 172.23.2.1/255.255.224.0 mac_offset 0
vlan 1 ip vrrp 10 address 172.23.1.10
vlan 1 ip vrrp 10 backup-master enable
vlan 1 ip vrrp 10 holddown-timer 60
vlan 1 ip vrrp 10 priority 110
vlan 1 ip vrrp 10 enable

vlan 4 ip create 172.23.227.2/255.255.255.0 mac_offset 3
vlan 4 ip vrrp 20 address 172.23.227.1
vlan 4 ip vrrp 20 backup-master enable
vlan 4 ip vrrp 20 holddown-timer 60
vlan 4 ip vrrp 20 priority 110
vlan 4 ip vrrp 20 enable

When creating the VRRP you need to ensure that both switches use the same VRRP ID -- above examples 10 & 20.

Which is backup and which is master is determined by the VRRP priority where switch 2 is the master.

We are also using backup-master feature which is a non standard VRRP feature unique to Nortel. Basically whichever switch receives a layer 3 packet will handle it directly rather than bouncing it over to the master.

Just a note -- if you don't want your log file filled up with VRRP entries, one every 60 seconds HOLD DOWN, change the send trap flag under the JDM - IP Routing / VRRP / Globals
