Hello everybody,
On my ASR907 Router, with following software:
Cisco IOS XE Software, Version 16.09.02
Cisco IOS Software [Fuji], ASR900 Software (PPC_LINUX_IOSD-UNIVERSALK9_NPE-M), Version 16.9.2, RELEASE SOFTWARE (fc4)
I can't achive remote L3 mirroring with ERSPAN feature. I configure it as below:
interface GigabitEthernet0/2/5
description monitor
mtu 9000
ip address 10.123.234.1 255.255.255.0
negotiation auto
monitor session 1 type erspan-source
source interface Gi0/2/0
destination
erspan-id 100
ip address 10.123.234.5
origin ip address 10.123.234.1
!
On source port there is some traffic:
#sh int gi0/2/0 | i minute
5 minute input rate 2000 bits/sec, 3 packets/sec
5 minute output rate 2000 bits/sec, 3 packets/sec
but on mirrored port there is silence:
#sh int gi0/2/5 | i minute
5 minute input rate 1000 bits/sec, 2 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
The status of mirroring session seems to be ok:
#sh moni ses 1
Session 1
---------
Type : ERSPAN Source Session
Status : Admin Enabled
Source Ports :
Both : Gi0/2/0
Destination IP Address : 10.123.234.5
Destination ERSPAN ID : 100
Origin IP Address : 10.123.234.1
I tried also to establish any link between 2 routers, but also no success.
I increased MTU on outgoing interface, but there is totally nothing comming out.

The router seems to ignore configured IPs, and it doesn't matter if the session will be terminated locally or on another router.
Does anyone configured ERSPAN successfully on ASR90x Series routers?
