An ISP has a BGP-free MPLS LDP core. The ISP provides L2VPN and L3VPN services over the
MPLS core. The ISP network monitoring tools show that whenever a new link or a link that was
taken out for maintenance is brought up, it causes a traffic outage lasting for a few seconds for
VPN and Internet traffic. What are the first two steps to mitigate this problem? (Choose two.)
A.
Configure LDP session protection in the core.
B.
Configure the LDP IGP sync feature on the core routers.
C.
Configure link dampening on the interface before bringing up the link.
D.
Configure route dampening on PE routers.
E.
Configure carrier-delay down 60 on the interface before bringing the link up.
