[c-nsp] BGP Route Reflector Case

[Sebastian Becker]

Hi Curtis,

you can have at least (because official supported) two bgp instances on (for example) an ASR9001-S with IOS-XR:
http://www.cisco.com/c/en/us/td/docs/routers/crs/software/crs_r4-2/routing/configuration/guide/b_routing_cg42crs/b_routing_cg42crs_chapter_01.html <http://www.cisco.com/c/en/us/td/docs/routers/crs/software/crs_r4-2/routing/configuration/guide/b_routing_cg42crs/b_routing_cg42crs_chapter_01.html>

Release 4.2.0

	•  BGP Multi-Instance/Multi-AS Support 

Another idea can be a virtualised IOS-XR:
http://www.cisco.com/en/US/docs/ios_xr_sw/ios_xrv/install_config/b_xrvr_432_chapter_01.html <http://www.cisco.com/en/US/docs/ios_xr_sw/ios_xrv/install_config/b_xrvr_432_chapter_01.html>

You still need to peer with every instance you need to create reachability.
