LAST WEEK'S ANSWER:
Answer: d
Topic Domain: 4b
Issues:
What is the logic followed by the route map used in this BGP
configuration? What is the default MED value for routes?
Solutions:
Notice that this route map sets the MED for certain prefixes.
Specifically 10.10.10.0/24 will be set to 100 and 10.11.10.0/24 will be
set to 200. Here the prefix in question 10.10.11.0/24 will be matched by
the final "catch all" route map statement. It will have the default MED
of 0. Examine the output as these routes appear on the BGP peer.
R2#show ip bgp
BGP table version is 4, local router ID is 172.16.2.2
Status codes: s suppressed, d damped, h history, * valid, > best, i -
internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
