You probably won't like my answer "that depends". If the effect of the action on router 1 is to cause router 1 to use a routing/signaling protocol to make things happen in the network, then the answer may be 1. If the changes cannot be effected in that way, then the client may need to talk to multiple routers to make the different things happen on each router. And in between there lies the case of needing to touch some, but not all routers because other routers in between are worked on by signaling/routing. So the answer is 1 <= #agents <= #routers And that answer is modulo there being only one agent on each router :-) For (crass) examples of the above I give you: Set up an LSP using RSVP-TE (just talk to head-end router) Set up an end-to-end static route (talk to each router) Set up a multi-segment pseudo-wire (talk to the T-PEs and the S-PEs) Adrian _______________________________________________ i2rs mailing list [email protected] https://www.ietf.org/mailman/listinfo/i2rs
