ACE with FT: configure alias IP on bvi interfaces?

[martabaro]

Hello,

We have two ACE modules configured for FT and bridge mode. Do we have to configure alias IP addresses on the bvi interfaces (I mean the bvi interfaces where client and server vlans are bridged)?.

interface bvi 125

  ip address 10.10.10.3

  no shutdown

interface vlan 125

  bridge-group 125

  ...

interface vlan 126

  bridge-group 125

  ...

OR:

interface bvi 125

  alias address 10.10.10.3

  no shutdown

interface vlan 125

  bridge-group 125

  ...

interface vlan 126

  bridge-group 125

  ...

Thanks and kind regards

This might help.

Configuring an Alias IP Address

When configuring a redundant configuration with active and standby modules, you can configure a VLAN interface that has an IP address that floats between active and standby modules. To configure a floating address for the BVI, use the alias command in its interface configuration mode. The syntax for the command is:

alias ip_address mask

The ip_address mask arguments are the address and subnet mask of the interface. Enter the IP address and subnet mask in dotted-decimal notation.

For example, to configure an IP address and mask for a BVI, enter:

host1/Admin(config-if)# alias 10.0.0.15 255.255.255.0

To delete the alias IP address from a BVI, enter:

host1/Admin(config-if)# no alias 10.0.0.15 255.255.255.0

Typically you do not need alias addresses in bridged contexts. They are used as next hops in a routed context environment.

Thanks to both!

My doubt was with the only Ip address i will have to configure, the one that belongs to the vlan interfaces themselves (the unique IP for client and server vlan interfaces).
