Configuring A Vpn Routing Session - Cisco Catalyst 9500 series Configuration Manual

Configuring IP Unicast Routing

Configuring a VPN Routing Session

Routing within the VPN can be configured with any supported routing protocol (RIP, OSPF, EIGRP, or BGP)
or with static routing. The configuration shown here is for OSPF, but the process is the same for other protocols.
Note To configure an EIGRP routing process to run within a VRF instance, you must configure an
autonomous-system number by entering the autonomous-system autonomous-system-number
address-family configuration mode command.

Configuring a VPN Routing Session
Purpose
Enters global configuration mode.
Enables OSPF routing, specifies a VPN
forwarding table, and enter router
configuration mode.
(Optional) Logs changes in the adjacency state.
This is the default state.
Sets the switch to redistribute information from
the BGP network to the OSPF network.
Defines a network address and mask on which
OSPF runs and the area ID for that network
address.
Returns to privileged EXEC mode.
