Re: Community IN BGP...

Thanks John,
 I got it.

 If a given router does not understand or use the community attribute, the
 route is not dropped and the community is passed along in updates sent to
 other BGP neighbors.  The statement you originally posted simply says this:
 Any given router need not use the community attribute, but that information
 must remain intact so that other routers might make use of it should they
 decide to do so.

 A BGP community is strictly an administrative attribute.  It has zero effect
 on routing if your router is not configured to use that information.
 However, your router needs to forward that information intact to other
 neighbors in case they need it to enforce whatever routing or filtering
 policies they have implemented.

 HTH,
 John

   I could understand this since this is a transitive attribute and
 therefore it can
   transit the routers and can be passed.
   But there is a condition imposed by whereby it says that the remote
 router maynot
   understand the community but it shall be configured to propogate it to
 the next hop
   destination or transit router else by default the communities are
 dropped. Now if the
   communities are dropped "does this mean that the route is dropped" since
 the coomunity
   attribute is resposible for the routes ...

 able to
to use it.
   
I'm sure someone will correct me if I have the wrong.

  What does this mean :

  "IF A ROUTER DOESNOT UNDERSTAND THE CONCEPT OF COMMUNITIES IT WILL
 DEFER
TO THE NEXT ROUTER"

  Please help.

Re: EMUTEL LITE setup

2001-02-19 Thread mbgupta

Are you using Emutel with the Europe or NA image. I have used the switch using the
Europe image and it works fine. Just plug in the BRI of two routers to the two ports of
Emutel and dial make a call from the once router to other and if you need to change the
predefined numbers then go into the software configuration menu and chose the BRI port
and change the no. of digits and the Number you wish. You are then all set to go.
Thanks

 I'm going to configuring my ISDN test bed this evening and I've got two
 2503's, two NT1's and an EMUTEL LITE ISDN simulator.  I think I've got the
 routers set-up right, the NT1 seems to be just a plug in thing, but I'm not
 looking forward to configuring this ISDN simulator.  It looks like by
 default the SPIDs are disabled, and there's probably a bunch of other
 settings that need to be set properly.  Can anybody save me several hours of
 frustration by letting me share your experience in setting up this box?  Let
 me know...
