Configuring A Vpn Routing Session - Cisco 3845 - Security Bundle Router Software Manual

Chapter 29 Configuring IP Unicast Routing
used to look up the destination IP address. These changes are backward-compatible and do not affect
existing behavior. That is, you can use the source-interface CLI to send packets out a particular interface
even if no VRF is configured on that interface.
To specify the source IP address for FTP connections, use the ip ftp source-interface show mode
command. To use the address of the interface where the connection is made, use the no form of this
command.
Command
Step 1 configure terminal
Step 2 ip ftp source-interface interface-type
interface-number
Step 3
end
To specify the IP address of an interface as the source address for TFTP connections, use the ip tftp
source-interface show mode command. To return to the default, use the no form of this command.
Command
Step 1 configure terminal
Step 2 ip tftp source-interface interface-type
interface-number
Step 3
end

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.
To configure an EIGRP routing process to run within a VRF instance, you must configure an
Note
autonomous-system number by entering the autonomous-system autonomous-system-number
address-family configuration mode command.
Beginning in privileged EXEC mode, follow these steps to configure OSPF in the VPN:
Command
Step 1 configure terminal
Step 2 router ospf process-id vrf vrf-name
Step 3
log-adjacency-changes
Step 4
redistribute bgp
autonomous-system-number subnets
Step 5
network network-number area area-id
OL-23400-01
Purpose
Enter global configuration mode.
Specify the source IP address for FTP connections.
Return to privileged EXEC mode.
Purpose
Enter global configuration mode.
Specify the source IP address for TFTP connections.
Return to privileged EXEC mode.
Purpose
Enter global configuration mode.
Enable OSPF routing, specify a VPN forwarding table, and enter router
configuration mode.
(Optional) Log changes in the adjacency state. This is the default state.
Set the switch to redistribute information from the BGP network to the
OSPF network.
Define a network address and mask on which OSPF runs and the area
ID for that network address.
