Hi!, i'm looking for routing between GoblalRoute and any VRF in VSP4450 on 7.1.1.0 VOS.

This is my config example:
- add GlobalRoute routes to a VRF:
router vrf vrf-red
Isis accept i-sid 0
exit
isis apply accept vrf vrf-red

*** Where i-sid 0 is the Global Route Table.

- add routes from vrf to GRT:
router isis
accept i-sid xxxx
exit
isis apply accept

This works but i can't make the GlobalRoute learn the 0.0.0.0/0 route from the VRF. Can anyone help me?.

Thanks!,
Joan Ale

Assuming the default route you listed is located in your vrf-red and without seeing the entire script, I would guess you haven't redistributed the static route for your VRF.
"isis apply redistribute static vrf vrf-red"

hope this helps.

Hello sdockham, thanks for you help! i get the next output when y apply the redistribute. You think i need to redistribute on globalRT too?.

NEW-VSP-01:1(config-isis)#isis apply redistribute static vrf aasa
Error: ip redistribute entry is not found

EDIT:
router vrf vrf-red
isis redistribute static
isis redistribute static enable
isis apply redistribute static vrf vrf-red

I apply those commands and it's working now, i gonna make some routing test. Thanks again!.
