CLI commands invoked on Juniper ERX devices
Because the MPLS and VPN MIBs are not supported by Juniper ERX devices and virtual routers, the
MPLS Topology Server
uses CLI discovery exclusively to discover MPLS topology
objects and their relationships for these devices.The CLI show commands that are invoked for
MPLS discovery on Juniper ERX devices and virtual routers are listed in CLI commands for discovery on Juniper ERX devices.
Command | Description | Comment |
|---|---|---|
CLI commands for MPLS discovery | ||
show mpls l2transport interface brief | Shows status and configuration
for Layer 2 services over MPLS, also known as Martini or Layer 2 transport, on the device or on specific interfaces. | |
show vlan subinterface | Shows status and configuration for a specified VLAN subinterface, or for all VLAN subinterfaces
that are configured on the device. | |
show mpls for brief | Shows summary information for MPLS labels that are being used for forwarding. | |
show mpls forwarding brief | Shows configuration and statistics for LSPs. Entries may have
only an "In" line, only an "Out" line, or both "In" and "Out" lines. Entries with only an "In" line refer to egress LSPs; entries with only an "Out" line refer to ingress LSPs; and entries with both "In" and "Out" lines refer to transit LSPs. | |
show mpls interfaces brief | Shows the MPLS interfaces, their IP addresses, protocol, and status. | |
show route table inet.3 | Shows the route entries in the inet.3 table. | Used in conjunction with the “show mpls forwarding brief” command to discover LDP LSPs and TE LSPs, and to discover the stacking of LDP LSPs on TE LSPs. |
show route table mpls.0 | Shows the route entries in the mpls.0 routing table. | |
show rsvp session detail | Shows detailed RSVP session information. | |
show mpls lsp detail | Shows information about configured and active dynamic LSPs in which the device participates. Using
the “detail” keyword displays detailed LSP information, including all current state information and all parameters and counters that are part of the LSP. | |
show mpls lsp detail ingress | Same as “show mpls lsp detail” command above. Using the “ingress” keyword displays sessions that originate from the device. | |
show ldp neighbor | Shows peer LDP speakers, their IP address, and the interface
used to exchange labels with them. | Used to discovernon-targeted LDP adjacencies. |
CLI commands for L2VPN discovery | ||
show ip bgp vpnv4 all fields best out-label peer next-hop extended-communities | Shows IP BGP prefixes, outgoing labels, peer IP addresses, next hop addresses, and extended communities. Entries with Next-hop
0.0.0.0 are ignored. | |
show ldp neighbor | Shows peer LDP speakers, their IP address, and the interface used to exchange labels with them. | Used to discoverTargeted LDP adjacencies. |
show mpls l2transport interface brief | Shows status and configuration information about Layer 2 services over MPLS. Using the “brief” keyword displays limited interface information. | Used to discover
VPWS and VPLS instances, and to discover and map VLANs to discovered VPLS instances. |
show vlan subinterface | Shows configuration and status information for all VLAN subinterfaces that are configured on the device. | |
show mpls
ldp vpls | Shows VPLS instance name, VPLS Id, remote PE, in-label, and out-label information | |
show vpls connections details | Shows connection information for all VPLS instances that are configured on the device. Using the “details” keyword
displays detailed configuration and status information for VPLS connections. | |
CLI commands for L3VPN discovery | ||
show ip vrf detail | Shows the VRF tables and their associated route distinguishers (RDs) and interfaces. Each block in the output of this command starts with the keyword "VRF" followed by the VRF name and the route distinguisher. In some cases a VRF description will also appear. | |
CLI commands for BGP route reflector discovery (ERX) | ||
ip bgp neig | include REmote IP | Neighbor is a route reflect | ||
