Question
Given the diagram and the following information:
- Virtual Private Routed Network (VPRN) 5 spans the routers Point of Concentration (POC) 3-1 and 3-2 and the Multihead System (MLS) routers MLS1 and MLS2
- Multiprotocol Border Gateway Protocol (MP-BGP) is configured and operational
- Pseudowire status is signaled, as shown, on the ePipe/VPRN spoke Service Distribution Points (SDPs) What might you configure on the services illustrated to hold down the primary VPRN NodeB loopback interface static route in case of an intermittent or rapid spoke SDP failure and recovery?
