CCNP-to-CCIE Transition Kit; Route Lab 2; Task 7.6; Problem reaching
external "ISP" networks on R9 via R2,R4,&R5. I can reach them from R6.
Everything works as it should. Accourding to the DSG, I am only looking
to see if the default 0.0.0.0/0 route is in the table. It does not test
reach ability, and neither does the task say to test reach ability and
that it should be working. I'd imagine I would want to get out of the
network, or what's the point?
Starting on R9;
R9#sh run | sec router bgp
router bgp 65001
neighbor 173.16.121.6 default-originate
Then R6;
R6#sh ip bgp
BGP table version is 11, local router ID is 173.16.121.6

R6#sh ip route

I can reach the ExtraNet office over the frame relay link from the
small office and big office. I just can't reach the R9 networks from
ExtraNet switches, Small & Big office. The following shows reachability
from R6 to R9's networks;

R6(tcl)#exit
I checked my answers to the DSG, they look good. I even went as far as
to do exactly what the DSG did. And I still can't reach the networks
that are pingable above on R6 when doing the same on R2,R4,&R5. None of
the Cat switches can reach them either. I even tried to redistribute
using a prefix-list to only get the default route into OSPF from BGP;
!-- on R6
ip prefix-list DEFAULT_ROUTE seq 10 permit 0.0.0.0/0
route-map PERMIT_DEFAULT_ROUTE permit 10
match ip address prefix-list DEFAULT_ROUTE
exit
route-map PERMIT_DEFAULT_ROUTE deny 20
router ospf 65101
no default-information originate
redistribute bgp 65101 route-map PERMIT_DEFAULT_ROUTE subnets
The default route 0.0.0.0 doesn't even show up on R2,R4,&R5. So I tried
the following;
!-- on R6
router bgp 65101
neighbor 170.70.255.9 shutdown
exit
ip route 0.0.0.0 0.0.0.0 160.171.90.37 30
ip route 0.0.0.0 0.0.0.0 160.171.90.41 30
router ospf 65101
redistribute static route-map PERMIT_DEFAULT_ROUTE subnets
exit
again the default route does not show up R2,R4,&R5. any help would be
much appreciated (even knowing that it's not supposed to work would be
cool).
