My ISP supports RFC 4638 on my VDSL connection and requests me to set an MTU of 1508 on the VLAN interface and an MTU of 1500 on the PPPoE interface. I used this Cisco document and made the following change to my config: interface Ethernet0.6 encaps...

Hi Guiseppe, I was thinking the same thing but when I configured pppoe-client ppp-max-payload 1500the connection worked but fragmentation occurred when the size was > 1492 so a ping with size 1492 would work but a ping with a size of 1493 would not. ...

Works great, did need to re-add ssl trustpoint to gateway, reload router and import certificate again but other than that no problems.
