Chapter 3 Configuring Remote Access to MPLS VPN
Configuration Tasks for RA to MPLS VPN
Note You cannot simultaneously configure a BBA group for PPPoE and a VPDN group for PPPoE. If you
configure a BBA group and then you configure a VPDN group, the protocol command in VPDN
accept-dialin configuration mode does not include an option for PPPoE (for example, you cannot specify
the protocol pppoe command). Use the no bba-group pppoe command to re-enable the pppoe option
for the protocol command.
