Aw: Re: bgp router with multi asn's - neighbor config ?

[Kai]

Hello,

Many thanks already for your input!
While working further on the topic, I stubled about one more uncertainty - maybe some kind soul can provide me with one or two additional answers? :)

In this example, that would supposedly perfectly suit my problem, the "router id" config param is used _inside_ a "protocol bgp" block. The version of the "BIRD User's Guide" I have (it doesn't tell it's version, quite new, pdf 49 pages) documents the use of "router id" only _outside_ of "protocol" blocks.

So, (1) should it work to use "router id" inside a "protocol" block (and different router ids inside different blocks), and (2) is this use of the "router id" directive officially supported?

(Regarding 1: it apparently does!?)

Best regards, Kai
