Prerequisites for dynamic local peer IP
• Specify IKE aggressive mode with the initiate mode aggressive command when
entering the ISAKMP peer information (see Configuring ISAKMP peer information on
page 489).
Gxxx-001(config-peer:149.49.70.1)# initiate mode aggressive
Done!
• Specify the local device by its FQDN name, using the self-identity command, when
entering the ISAKMP peer information (see Configuring ISAKMP peer information on
page 489). For example:
Gxxx-001(config-peer:149.49.70.1)# self-identity fqdn vpn.avaya.com
Done!
• Specify the local address by name in the ip crypto lists, using the local-address
command (see Configuring crypto lists on page 495). You must specify the local address
by interface name. For example:
Gxxx-001(Crypto 901)# local-address FastEthernet 10/3
Done!
Configuring dynamic local peer IP on a PPPoE interface
Procedure
1. Enter the context of the FastEthernet interface.
For example:
Gxxx-001(config)# interface fastethernet 10/3
Gxxx-001(config-if:FastEthernet 10/3)#
2. Enter the following commands in the context of the interface: no ip address,
encapsulation pppoe, and ip address negotiated.
Gxxx-001(config-if:FastEthernet 10/3)# no ip address
Done!
Gxxx-001(config-if:FastEthernet 10/3)# encapsulation pppoe
Done!
Gxxx-001(config-if:FastEthernet 10/3)# ip address negotiated
Done!
3. Exit the context of the interface, and set the interface name as the next hop.
For example:
Gxxx-001(config-if:FastEthernet 10/3)# exit
Gxxx-001(config)# ip default-gateway FastEthernet 10/3
Done!
Note:
PPP over Ethernet (PPPoE) is a client-server protocol used for carrying PPP-
encapsulated data over Ethernet frames. You can configure PPPoE on the
Branch Gateway’s ETH WAN Fast Ethernet port. For more information about
PPPoE on the Branch Gateway, see Configuring PPPoE on page 252.
