Hey all,
Question:
1) On a router with multiple outbound paths, if fast switching (or CEF) =
is enabled and outbound traffic comes through towards a given =
destination, is all traffic for that same destination then locked to the =
same path untill the route cache is cleared?
2) If the above is yes, how long does the router maintain its route =
cache?
Purpose:
We have a 7507 that will be running BGP over 2 T1's. We are attempting =
to establish load balancing both inbound and out. Halabi (2nd Ed.) in =
Chapter 7 warns that to do this one must be familiar with the different =
methods of switching. Thus I am studying to find the pro's and cons of =
each. CEF or fast switching sounds about right, however, the above =
question was raised as I was discussing this with our lead engineer.
Thank You
Adam
