Which three options are restrictions for MPLS VPN BGP Local Convergence? (Choose three.)

A.
The MPLS VPN BGP Local Convergence feature affects only traffic that is exiting the VPN.
Therefore, it cannot fully protect traffic end-to-end by itself.

B.
This link protection can be initiated during a HA SSO. But links that were configured with this
protection before the switchover begins remain protected after the switchover.

C.
The MPLS VPN BGP Local Convergence feature for IPv4/IPV6 supports the eBGP, RIP,
EIGRP,OSPF, and dynamic routing protocols.

D.
Any next-hop core tunneling technology that is supported by BGP is also supported for
protection, including MPLS, L2TPv3, and IP/GRE. CSC protocol between the PE and CE is also
supported. Interautonomous system option A (back-to-back VRF) is supported because it is
essentially the same as performing the PE-CE link protection in both autonomous systems.
However, interautonomous system options B and C protection are not supported.

E.
If you perform an in-service software downgrade from an image that does include this link
protection to an image that does not support this feature, active protection is halted when BGP
routes are refreshed.
