I have lots of respect for my colleague Leo but I wonder about the basis for his assertion that the ability to change the bandwidth is based on the feature set that is running. For mGRE tunnel interfaces, since there is no fixed tunnel destination, some of the previous checks for P2P tunnels are not applicable. (Optional) VRF name. This means that each tunnel endpoint does not keep any information about the state or availability of the remote tunnel endpoint. show mpls traffic-eng tunnels fast-reroute [summary]. ipv4 [ Configure unreserved UDP port numbers for IPv6 payload.

Configure separate UDP port numbers for IPv4, IPv6, and MPLS. Slot or port number. The interface that anchors the tunnel source is down. So using the commands mentioned above you can easily verify whether or not an IPSec tunnel is active, down, or still negotiating. ** - Found in IKE phase I aggressive mode. (Optional) Destination IP address for forwarding adjacency tunnels. device # show ip interface tunnel 64 Interface Tunnel 64 port enabled port state: UP ip address: 223.224.64./31 Port belongs to VRF: default-vrf encapsulation . (Optional) Displays the summary information. A valid tunnel source consists of any interface that is itself in the up/up state and has an IP address configured on it. This example shows how to display the contents of all current IP prefix lists: To display information about the Routing Information Protocol (RIP), use the show ip rip vrf command. The maximum size is alphanumeric 32 characters. (Optional) Specifies the destination port information. This added an additional check, which keeps such tunnel interfaces in the line protocol down state until the redundancy state changes to ACTIVE. This example shows how to display the MPLS MVPN MDT route information: To display information about a static virtual routing and forwarding (VRF) route, use the show route static vrf command. show crypto ipsec client ezvpn - should show a state of IPSEC ACTIVE; If the VPN tunnel is not up, issue a ping to AD1 sourced from VLAN 10. This example shows how to display the LDP configuration parameter: To display the MPLS operations and management (OAM) information, use the show mpls oam command. This allows for the installation of an alternate (floating) static route or for Policy Based Routing (PBR) in order to select an alternate next-hop or interface. This is needed because once the configuration is sent to the TFTP server, the pre-shared key appears as clear text (instead of ***** , as in the show run command). VRF name. They have chosen a value for tunnel interfaces that is quite low (and I am not sure why this is). The supported range is from 1000 through 64000. Here are the reasons an mGRE tunnel line protocol can be in a down state: When a tunnel source IP address is configured as a redundancy IP address (for example, a Hot Standby Router Protocol Virtual IP (HSRP VIP) address), then the tunnel interface state tracks the redundancy state. The maximum size is 32 alphanumeric characters. Lastly, we define the Tunnel Destination IP address.

Show Commands and Outputs This section provides information regarding show commands and their outputs in support of Cisco Ultra Traffic Optimization. Traffic engineering (TE) ingress address. When I am configuring a router that will run EIGRP over GRE tunnels I do routinely configure a bandwidth for the tunnel. High label value. This usually happens when the tunnel is misconfigured with a Next Hop Server (NHS) that is its own IP address. The tunnel bandwidth doesn't limit the actual bandwidth for tunnel interface. Configure unreserved UDP port numbers for MPLS payload. tunnel show mpls ldp igp sync [interface ethernet slot/chassis number]. You can use the bandwidth command in interface configuration mode of the tunnel to change this default value to something that better reflects your operational environment. The supported range is from 1000 through 64000. The range is from 0 to 2147483647. To remove this configuration, use the no prefix of the command: The following example shows how you can configure unique GUE port numbers to decapsulate IPv4, IPv6, and MPLS packets using Instance tag that is a case-sensitive, alphanumeric string up to 20 characters.

(Optional) Displays the neighbor's IP address. How can I activate it? Specifically, if the line protocol for an interface is changed to down, then any static routes that point out that interface are removed from the routing table. To configure unique GUE port numbers to decapsulate IPv4, IPv6, and MPLS packets using UDP, use the hw-module profile gue udp-dest-port ipv4 ipv6 mpls command in XR Config mode on the destination router. No specific guidelines impact the use of this command. (Optional) Specifies the path based on a source port. To remove this configuration, use the no prefix of the command. This example shows how to display RSVP fast reroute information: To display the Resource Reservation Protocol (RSVP) hello client label switched path (LSP) database, use the show ip rsvp hello client lsp command.
