Probleme cisco c888

I cannot connect my router: C800 Software (C800-UNIVERSALK9-M), Version 15.7(3)M2 to my Genieacs.
My Genieacs is functional because I already have Mikrotik routers on it.

I have configured my Cisco this way:

cwmp agent
management server url http://11.XXX.0.2:7547
interface Ethernet0
cwmp wan
interface Ethernet0.2900
encapsulation dot1Q 2900
pppoe enable group global
cwmp wan
pppoe-client dial-pool-number 10
interface Dialer10
ip vrf forwarding MPLS
dialer pool 10
dialer-group 10
cwmp wan default
cwmp agent
enable download

But when I see the session I have a problem:

Routeur-C888#sh cwmp session
CWMP Agent status: Enabled
No CWMP Session currently running
Management Server: http://11.XXX.0.2:7547
Connection Request URL:
Last successful connection request at time:
Last successful session at time:
Last failed session at time: 13:41:20 CEST Thu May 27 2021
Session retry count: 6


Hi, try to ping (the ACS IP) from the cisco cli … do you get reply ?

What does wireshark say, when you trace the connection?

Yes I ping it but I have to specify the VRF it disturbs?

#ping vrf MPLS 11.XXX.0.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 11.XXX.0.2, timeout is 2 seconds:
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/7/8 ms

Yes, that’s the problem I think, but a wireshark packet capture, like JonasGhost mentioned, could indicate exactly if this is the case. To solve, see if you have any options to specify the vrf at the cwmp agent config, move the ACS outsite of the VRF, or try to route between global and vrf with some static routes (not sure if this works, I don’t have a cisco device to test):

ip route vrf MPLS global
ip route Dialer10 <gateway>
