Hi Rajesh:
There are four reason Anycast address cann`t work.
1:If using anycast address,When the AC interface of egress PE is
failure,traffic will detour.
2:if using anycast address,The overlay path is limited by the underlay path,if
VPN1 wants to prefer PE1,VPN2 wants to prefer PE2.It cann`t work.
3: if using anycast address,CE1 is connect to PE1/PE2,CE2 is connect PE2/PE3，It
will be hard to develop.
4: if using anycast address,PM is unavailable.

Hi All,
Egress protection can be achieved using Anycast address, why this new solution
is required ?
Thanks
