What must you do to solve the problem?

Change the route distinguisher in both routing instances to the same value.

Use the next-tableconfiguration statement for static routes in the corresponding routing instances.

Use BGP instead of static routing between the CE and PE devices.

Use the auto-exportcommand in both routing instances.

NO.61 Which two statements are correct about Opaque LSAs in OSPF? (Choose two )

Type 9 LSAs are used for graceful-restart and have link-local scope

Type 11 LSAs are used for MPLS label exchange and have link-local scope

Type 10 LSAs are used for MPLS traffic-engineering and have area scope.

Type 11 LSAs are used for MPLS traffic-engineering and have area scope

NO.62 Exhibit:

You have a Layer 3 VPN established between PE-1 and PE-2 as well as between PE-1 and PE-3. You are using a route reflector (RR-1) to distribute VPN routes to your IBGP peers. You are asked to ensure that only relevant routes are sent from RR-1 to each of the PE routers.
Referring to the exhibit, which statement is correct?

You should use VRF export policies on RR-1 to control which routes are sent to each PE router.

You should use route target filtering on RR-1 and all the PE devices to control which routes are sent to each PE router.

You should use firewall filtering on RR-1 and all the PE devices to control which routes are sent to each PE router.

You should use route target filtering only on RR-1 to control which routes are sent to each PE router.
