rje protocol

[Rich Schaller]

Can anyone tell me what this protocol is used for?  I'm seeing heavy
traffic for one of our clients on ICMP port 5 originating from a Cisco
router destined for their firewall and one of their servers behind the
firewall.  All packets are being blocked, but it's eating up their logs.
Any ideas?  Are there services enabled on the Cisco that need the rje
protocol?

Thanks,
Rich Schaller
