Link loss forwarding

[Antonio_1_2]

Hello,

does Cisco support "Link loss forwarding" on one of its platforms?

Is there maybe any other similar feauture ( i.e. like BFD over ethernet) which could do the same thing?

foe example:

LAN1---cisco1-----layer2_NETWORK---cisco2--- LAN2

some feature which could detect failure somewhere in a layer2 network between cisco1 and cisco2 and

then bring down ports toward LAN1 and LAN2.

Thanks in advance,

A.

Hello Antonio,

you should look for CFM Connectivity Fault Management according to metro ethernet forum standards. 802.1ah Ethernet OAM and CFM

It  comes in two flavors link level fault management  or logical level fault management ( roughly single Vlan level EVC in MEF terms).

see

CFM over EVC on ES linecards
