15.3(1)S introduced the support for BGP PIC Core feature. BGP PIC Edge will be added in a future release (tbd)
For reference or more info open a TAC case mentioning internal bug CSCty90567 which introduced it.
We can configure PIC Core with no problem:
ME3600-1#sh run | i cef
cef table output-chain build favor convergence-speed
But we can configure PIC Edge too:
ME3600-1(config-router-af)#bgp additional-paths ?
install Additional paths to install into RIB
select Selection criteria to pick the paths
Can you please clarify if both PIC are supported ? I can´t access the DSTS since it is internal to Cisco.
ME does NOT support BGP PIC Core or Edge today. The feature is in roadmap for next year.
The CLIs are available due to platform independent commands. There is no platform code avaialble today to support the feature in hardware.
