Hello Friends,

   I have got some querry related with secondary addresses and
domai-wide address of router. Let me tell you what is going on
in my mind:
 (a) Let's say we are configuring a routre with 8 or n ports. Then what
do we do:
(i) for each port we assign some ip address. It can be different on
each port if each port of router is connected to different networks.
(II) In that case maximum addresses possible are n which correspond
to no. of ports of the router.

   Then what is all about primary and secondary addresses.
Domain wide addresses are mentioned on page no. 107 of RFC 4601.
("The source address used for unicast messages is a domain-wide reachable
address; the source address used for multicast messages is the link-local
address of the interface on which the message is being sent.").
