BDI Template 8200

[vin.marco]

Is it possible to configure redundancy between a clustered firewall and a Cisco 8200 router operating in Template mode using Cisco vManage? Specifically, can this configuration — including the creation and management of BDI interfaces — be implemented exclusively through the Templates provided by vManage?

Hello @vin.marco,

BDI is unfortunately not supported for cEdges. See the following documentation for bridging in Cisco SD-WAN: https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/bridging/ios-xe-17/bridging-book-xe/m-bridging-xe-sd-wan.html 

You can however make it work if you use routed links instead. If you can share a bit more about the setup we might be able to help you figure out how this can be done in the best way possible.

What I’m trying to achieve is a redundant setup between two Cisco 8200 routers, each connected to a different MPLS network. The firewalls behind them are configured in a cluster, so I would like to provide LAN-side redundancy as well, according to the diagram.

Maybe you can try to do it through cli feature? I tried to configure on the C-NIM-8T (it has two L3 interfaces)

interface GigabitEthernet0/1/6
 description -I- ### LAN
 no ip address
 load-interval 30
 no shutdown
 negotiation auto
 service instance 10 ethernet
  encapsulation untagged
  bridge-domain 10

interface GigabitEthernet0/1/7
 description -I- ### LAN
 no ip address
 load-interval 30
 no shutdown
 negotiation auto
 service instance 10 ethernet
  encapsulation untagged
  bridge-domain 10

interface BDI10
 description -L3- ### BDI LAN
 ip address 192.168.100.1 255.255.255.0

but I would recommend that you use LACP towards each FW and CNIM-8 T to the ISP (it has two L3 interfaces) to connect to the ISP. Just because it is supported

It’s definitely possible via CLI — I’ve also reviewed the documentation. However, my goal was to configure everything through Templates. At this point, I’ll try proceeding with LACP. Thank you.
