A.Graceful restart allows session information recovery without disruption to the network.
B.A node can perform a graceful restart to help a neighbor recover its state. The label bindings are kepton state information， which helps the failed node recover faster and does notaffect the current for wardtraffic.
C.Graceful restart allows a node to recover state from its neighbor when there is no RP or before thedevice undergoes SSO.
D.Graceful restart does not allow session information recovery.
E.During a graceful restart， the router removes any stale prefixes after a timer for stale entries expires

A.The RT is a BGP extended community.
B.The RT is an 8-byte field that is prefixed to an IPv4 address to make it a unique VPNv4 address.
C.When a VPN route that is learned from a CE router is injected into BGP， one or more RTs are associated with it
D.The distribution of VPN routing information is controlled through the use of VPN RTs
E.When a VPN route that is learned from a CE router is injected into BGP， there is always one RT that is associated with it.

A.Static mapping is used when the remote router does not support Inverse ARP.
B.Frame Relay Inverse ARP requires LMI capability to construct an address to the DLCI mapping tableon the router.
C.Frame Relay Inverse ARP is disabled by default in Cisco IOS Software for all protocols that areenabled on the physical interface.
D.Inverse ARP does not work when LMI is disabled.
E.Frame Relay provides forward and backward congestion notification messages
