I plan to configure a PIX-515E running 8.0(3) with a Redundant outside interface (comprising of two physical Ethernet interfaces - active/standby), both connected to two ports on a 2611XM router. The PIX will be configured as such:
ip address xx.xx.xx.234 255.255.255.248
By doing this I wish to achieve interface controller (by distributing interfaces across multiple modules) and media redundancy.
I am struggling to comprehend how I should configure the interfaces on the 2611XM to work in this configuration.
The PIX will have a global IPv4 address assigned to the logical Redundant outside interface. The 2611XM presently has a single interface (Fa0/0) configured as follows (IPv4 address within the same globally assigned subnet as the PIX outside interface). The 2611XM has a Multilink PPP (multiple ADSL) connnection to the world.:
description "Link to PIX_outside"
ip address xx.xx.xx.233 255.255.255.248
no ip unreachables
no ip proxy-arp
ip nbar protocol-discovery
ip flow ingress
ip flow egress
ip virtual-reassembly max-reassemblies 64
ip route-cache flow
description "Face to world"
ip unnumbered FastEthernet0/0
Please can someone advise me as to how I should re-configure the 2611XM so that both physical interfaces (i.e. Fa0/0 and Fa1/0) are able to participate in a dual-link redundant configuration with the PIX.
Many thanks for your time and advice.
If I understand correctly u want to have the two interfaces of your router to be in the same broadcast domain.
I think the best would be configure IRB.
