Question is which is best to implement now in a new SP network with IS-IS core and MPLS/LDP?
As this is a brand new green field build still in roll out we have no requirements yet for any MPLS TE, as no services are currently scheduled to be run over the new network.
So, as a best practice am I ok to deploy IP FRR for IS-IS with LDP support from day one? Will this give me any problems in future if I need to build MPLS TE tunnels? Am on latest (last time I checked) IOS XR code, 4.0.3
I recently watched a Cisco Webinar on IP FRR, and it seems to imply that IP FRR is totally suitable for an MPLS/LDP infrastructure, but then reading various other documents would seem to suggest as this is an MPLS/LDP application other FRR technologies may be more suitable, so I came to the community to get real world suggestions and recommendations.
Routers are mix of ASR9001 and 9006.
