Re: Link Status

Hi Asif,

There's more than one way to do it but one method I would consider
suggesting is to look at IP SLA ICMP tests between the interfaces of you
routers that are facing the SP MPLS network and your NMS uses the RTTMON
SNMP MIB to verify connectivity.

This is the guide on CCO about IP SLA ICMP echo operations
http://www.cisco.com/en/US/docs/ios/12_4/ip_sla/configuration/guide/hsicmp.html
This should be the MIB of interest
http://tools.cisco.com/Support/SNMP/do/BrowseMIB.do?local=en&mibName=CISCO-RTTMON-MIBfor
your NMS to query

Cheers,
Adam
