[c-nsp] Ring Protocol

[Rubens Kuhl]

A little bird from C whispered me the following:

"I'd take a look at the ME-4924-10GE device (REP Supports ~50ms
failover), as well as this you have support for it on the larger devices
like the 7600.

4924 support for REP started in 12.2(44)SG -

7600 has supported REP since 12.2(33)SRC -

I stand corrected.
