About Virtual-Template interfaces for the use with pppoe (bras) functions. There are multiple routing protocols supported with lots options (eg. IS-IS, RIP etc. with BFD etc.), but there isnt any options to use ospf or ospf with bfd with it.
To the background: it is to speed-up the reachability betwen bras-router and client-router (ar1220) or full ospf usage . So, need to deploy “OSPF over PPPOE” for the function to detect failures faster as PPPoE/LCP.
IS-IS and RIP are configurable in Virtual-Template for PPPoE, but no option for OSPF.
To configure
BGPOverPPPoE, must assign a fixed IP address for CPE. Must design the
CPE IP address allocation in advance. Can do this on Radius server, assign a
fixed IP by the radius attribute “Framed-IP-Address” and “Framed-IP-Netmask”.
After decide the CPE IP address, then can configure BGP as normal.
For example, decide to assign
a fixed IP X.X.2.2 to CPE, after CPE login, can see below
