Difference between local-tloc/-list and tloc/-list

[dijix1990]

Where can I read about difference in action local-tloc/local-tloc-list and tloc/tloc-list, or maybe somebody can explain?

I think that set local-tloc is action which forces to change way via chosen tloc for some group of interest traffic or not?

Hi,

In data policy:

local-tloc or list is primary local TLOCs for forwarding. If none of local TLOC available from the list, then router fallbacks to normal routing (this can be prevented, if you also set "restrict" besides local-tloc. Then action will be drop). Note that, here remote-TLOC is decided by routing table.It is loose logic.

remote-tloc or list enforces remote TLOCs. If none of TLOC from the list available, then drop happens. It is strict logic.

In control policy:

There is no local-tloc in the list of actions, only TLOC which changes TLOC information in OMP route. Plus, it requires set-vpn command.
