Register VG224 using SCCP and redundent links

[dan hale]

Hello all, I have several VG224s that I would like to have some redundancy. I decided to use both fastethernet interfaces ( differnt subnet's of course) and have our Call Manager register via SCCP to its loopback address.

Well apparently loopbacks dont have a MAC address.

Is there a way to accomplish this and still use both interfaces and have it register via SCCP?

Thanks,

Dan

Personally I don't think it's very important in a sane network, but you can use the following

bridge irb

bridge 1 protocol ieee

bridge 1 route ip

interface fa0

no ip address

bridge-group 1

interface fa1

no ip address

bridge-group 1

interface bvi 1

ip address ...

Then you use the single IP and MAC on BVI 1 for any purpose.

Spanning tree will block one the interface and if it goes down, will switch to the other.

Make sure the connecting switches interfaces are set to mode trunk, or auto.

Hi Paolo,

It looks like if I have redundant fast Ethernet routed links and use

sccp local Loopback 0

It will register the FXS port and stay registered even if the link is down. When I associate the mac address of the VG I do have to use one of the FA ports.

Thanks,

Dan

And that is why I suggested the technique above.

Thanks for the nice rating and good luck!
