IS IS Traffice supported on Cico PIX Firewall

[atolba]

Does any one knows if the Cisco PIX Firewall supports IS-IS Traffic.

PIX does not support any protocols except RIP, that too in passive mode, i.e. the PIX will not advertise routing updates, just learn.

If you want any protocol to pass through PIX, create a GRE tunnel through PIX and run the required protocol through GRE.

Following is an example of BGP/OSPF through PIX, you can use this as a template.
