I have BGP default route problem with this require:
Configure your network so that R8 will have a default route pointing to
R7. You are allowed to configure a default route on R7 but no
configuration is allowed on R8 for this step. This default-route should
only appear in R8's ( the original Workbook is R7's) routing table when
R7 is able to reach the 126.96.36.199 subnet. Is this possible ?
I am use the simple command under to let the R7 send out the default
route to R8.
neighbor 188.8.131.52 default-originate
but how to remove the default route when R7 can not reach the
184.108.40.206 subnet ?
the solution in that book use route-map like:
neighbor 220.127.116.11 default-originate route-map DEF
route-map DEF permit 10
match ip address 1
route-map DEF permit 20
access-list 1 permit 18.104.22.168 0.0.0.255
Is this correct ? I can not get any sense for this.
As I know the standard access-list is for packet source address match,
so that just match if the packet come from 22.214.171.124 subnet then
route-map match it. Right ?
