[c-nsp] 7200 irb/crb performance

[Richard Zheng]

Hi,

Our 7204/7206s are configured with multiple channelized T3 and ATM cards. We
use crb or irb bridge T1/ATM-PVC to vlan on the FE ports. So basically it is
used to terminate WAN traffic and bring it to our Ethernet only layer 3
switches. I see maximum bridge group number is 255. Anyone knows any
performance limitation? What if we disable the spanning tree on it? Are we
able to fully utilize the 255 bridges?

Any comments?

Thanks,
Richard
