MLPPP Session not pingable

Sun Jan 12, 2020 6:35 pm


I have the following configuration:

mikrotik --> Juniper vMX

I have configured an MLPPP session and I see the session UP on the vMX with all the subscriber details. The MikroTik is configured as the subscriber.

The configuration on the MikroTik is basic and is as follows:
/interface pppoe-client
add add-default-route=yes allow=pap disabled=no interface=ether1,ether2 max-mru=1500 max-mtu=1492 name=\
pppoe-out1 password=test user=MLPPP_Test

The route appears in the routing table.... assigned route to the MikroTik from the PPPoE server is and the loopback address on the server is

The MikroTik appers in the vMX routing table as "private/unicast" as it should.

Here is the routing table on the mikrotik:
0 ADS pppoe-out1 1
1 ADC pppoe-out1 0

So, all looks good there.

But, I cannot ping in either direction.... all routes appear to be in place but there is no data transfer between the two devices. When I ping from the MikroTik I see nothing hit the vMX. The problem is I cannot tell which end could be at fault.

Any help would be great.

I have completed investigations and have since found that the Juniper vMX will only support 1 member link for PPPoE MLPPP.
