Coming back to my original question: I converted part of my network to ROS V7.13.3 (and some testing with 7.14b8).
V7 seems fundamentally expanded to serve as the basis for years of features to come. Overall it seems close to being ready for the features I use.
Below is some random feedback of what I ran into.
Setup is: Network core routers with public BGP are on V6 still, two access routers are on V7. Config has underlying OSPF, MPLS on all routers, with LDP via Ethernet, GRE/IPSec and L2TP/IPsec interfaces.
- VPLS pseudowires: They work versus V6 endpoints, but not versus V7. When I lay RSVP-TE (CSPF or manual path) on top, then VPLS works. Could be config error. Might have something to do with LDP Neighbors having the Passive flag.
- RSVP-TE works with a simple test, using CSPF as well as manual (strict and loose) hops. Both Primary and Secondary pathes come up, but then the router gets confused about what primary and secondary is.
- Nasty: TE/Tunnel Path: The Hops do not work in Winbox - they do not generate correct syntax. CLI only. Grr... this one cost time.
- RSVP-TE without LDP? Should be possible, right?
- Issues with VPLS pseudowires not delivering traffic into bridges: I had to disable Fast Forward etc.
- Not clear: Is it still necessary to stop & start an LDP instance so that it picks up changes? I had the impression that was the case in V6.
- 7.14beta versions: meaning of the VRF interfaces is not clear. Adding it to the VRF then made things work (not related to MPLS etc.)
- BGP: NRLI accept filtering based on prefixes works for most simple cases, but is not enough. Prefix count is another one missing. MT denial can last for years... ... I know.
- I have not yet tested VPN4, as there seem to be issues with the Route Reflector (discussed elsewhere in this forum).
