Hi Joseph,
Thanks, do you have any pointers?
I think I should probably use the route-map to set the metric-type to E1
for each tag on R1 and R2. Then the OSPF domain will prefer the routes
through the correct path.
For example:
When R1 redistributes 212.18.0.0/22 into OSPF the metric for this prefix
is set to E1 via the route-map - all other routes will be E2 by default
When R2 redistributes 30.0.0.0/14 and 31.0.0.0/14 into OSPF the metric
for these prefix is set to E1 via the route-map - all other routes will
be E2 by default
This will mean that all OSPF routers prefer the E1 routes out of the
OSPF domain.
Am I along the correct lines for this?
