Thus spake Mike Wronski
Hrm.. I used it in a Cisco OSPF environment.. Further reading reveals that you are correct. OSPF does have a similar feature in the internal distance. This information is also NOT transmitted and is intended to help the receiver make its final routing decision based on available information.
Ya, for type 2 externals, if the external metric is equal, the internal distance is considered to pick a preferred path...if *those* are equal, I believe both paths are used with the normal equal-cost load-balancing mechanism in OSPF. You are correct that's it's not really transmitted via OSPF, but the internal distance is built based on the information transmitted in the OSPF protocol of course (basically the path cost from the system in question to the ASBR that originated the LSA). I suspect you already knew all this though. :) -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
