Add PPPoE Plugin
Supports 64K PPPoE sessions This plugin adds three graph nodes: 1) pppoe-input for PPPoE decapsulation 2) pppoe-encap for PPPoE encapsulation 3) pppoe-tap-dispatch for control plane process Below is the configuration to make PPPoE CP and DP work: vim /etc/vpp/startup.conf tuntap { enable ethernet name newtap } create pppoe tap tap-if-index 1 //Configure it after a subscriber's PPPoE discovery and PPP link establishment succeeds: create pppoe session client-ip 100.1.2.1 session-id 1 client-mac 00:11:01:00:00:01 show pppoe fib show pppoe session Change-Id: I73e724b6bf7c3e4181a9914c5752da1fa72d7e60 Signed-off-by: Hongjun Ni <hongjun.ni@intel.com>
