To specify the next IP address in the explicit path, use the next-address command in IP explicit path subcommand mode.
next-address A.B.C.D
Syntax Description
A.B.C.D Specifies the IP address in the explicit path.
To create routing and forwarding tables for a VRF, use the rd command in VRF submode.
rd route-distinguisher
Syntax Description
route-distinguisher Adds an 8-byte value to an IPv4 prefix to create a VPN IPv4 prefix.
To create a route-target extended community for a VRF, use the route-target command in VRF submode. To disable the configuration of a route-target community option, use the no form of this command.
route-target {import | export | both} route-target-ext-community
Syntax Description
import Imports routing information from the target VPN extended community. export Exports routing information to the target VPN extended community. both Imports both import and export routing information to the target VPN extended community. route-target-ext-community Adds the route-target extended community attributes to the VRF's list of import, export, or both (import and export) route-target extended communities.
To configure policy routing to verify if the next hop(s) of a route map is a CDP neighbor(s) before policy routing to that next hop, use the set ip next-hop verify-availability route-map configuration command.
set ip next-hop verify-availabilitySyntax Description
This command has no arguments or keywords.
To set a separate OSPF router ID for each interface or subinterface on a PE router for each directly attached CE router, use the set ospf router-id command in route-map configuration mode.
set ospf router-idSyntax Description
This command has no arguments or keywords.
To specify the maximum number of times a packet can be routed to the default router within shortcut-frame time before an MPOA resolution request is sent, use the shortcut-frame-count command in MPC configuration mode. To restore the default shortcut-setup frame count value, use the no form of this command.
shortcut-frame-count count
Syntax Description
count Shortcut-setup frame count. The default is 10 frames.
To set the shortcut-setup frame time (in seconds) for the MPC, use the shortcut-frame-time command in MPC configuration mode. To restore the default shortcut-setup frame-time value, use the no form of this command.
shortcut-frame-time time
Syntax Description
time (Optional) Shortcut-setup frame time in seconds.
To display Cisco Express Forwarding (CEF) adjacency table information, use the show adjacency command in EXEC mode.
show adjacency [detail]
Syntax Description
detail (Optional) Displays detailed adjacency information, including Layer 2 information.
To display information about private ATM virtual circuits (VCs), use the show atm vc command in privileged EXEC mode.
show atm vc [vcd]Private VCs exist on the control interface of a LSC to support corresponding VCs on an extended label ATM interface.
Syntax Description
vcd (Optional) Specifies the virtual circuit about which to display information.
To display which packets the line cards dropped or to display which packets were not express forwarded, use the show cef command in EXEC mode.

To display information about all sessions with VSI slaves, use the show controllers vsi session command in EXEC mode.
 |
Note A session consists of an exchange of VSI messages between the VSI master (the LSC) and a VSI slave (an entity on the switch). There may be multiple VSI slaves for a switch. On the BPX, each port or trunk card assumes the role of a VSI slave. |

session-num Session number. interface interface VSI control interface.
To display a one-line summary of each VSI-controlled interface, use the show controllers vsi status command in EXEC mode.
