Metric will be carried into an AS, but will not pass it to a 3rd AS. When the same update is carried to the 3rd AS, the MED value is set to 0.
Ps: an optional non transitive attribute must be deleted by a router that has not implemented the attribute. Sony. ------Original Message------ From: R.B.

Hope you experts donot bother to help me on this I know that BGP MED is having OPTIONAL NON-TRANSITIVE attribute. But I also know that MED is capable of moving to immediate next neighbour AS. MED is a hint to external neighbors about the preferred path into an autonomous system (AS) that has multiple entry points But since it is passing to next AS, How it is catagorized as NON-TRANSITIVE ? Since it is seen in neighbour AS, I thought it should be TRANSITIVE . But to my surprise it is OPTIONAL NON-TRANSITIVE Please help me where i have understood wrongly regards & Thanks in advance RBK Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=137451&t=137451 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Sent on my BlackBerry® from Vodafone _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
