[f-nsp] GRE tunnels on Brocade CER

[Mark Price]

Hi list,

I am considering deploying CER routers at two sites to handle BGP for
a few transit links, and OSPF for our internal network.

There will be a GigE point-to-point circuit connecting the two sites.

For backup in case that circuit is down, I am considering a GRE tunnel
over internet transit to carry OSPF traffic.

Does anyone have any experience running GRE tunnels on CER or related
families?  Is GRE handled in hardware or software?  Any performance
expectations?


Thanks,

Mark
