When a device uses CSPF to calculate the path for an LSP, it takes into account the administrative group to which an interface belongs. The user can specify which administrative groups the device can include or exclude for this calculation.
No interfaces are assigned to the administrative groups in the default mode.
MPLS LSP configuration mode (config-router-mpls-lsp-lsp_name).
MPLS router bypass LSP configuration mode (config-router-mpls-bypass-lsp-lsp_name)
MPLS router MPLS interface dynamic bypass configuration mode (config-router-mpls-if-ethernet-slot/port-dynamic-bypass)
Several administrative groups may be assigned to the LSP at the same time. The interface then must be a member of both groups.
Use the interface level include-all command to configure administrative groups for dynamic bypass LSPs to be created corresponding to a protected link.
The no form of the command removes the assigned interface.
MPLS is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only.
The following example specifies that the interface must be a member of both the "gold " and "silver " administrative groups to included in the path calculations for LSP tunnel1.
device# configure device(config)# router mpls device(config-router-mpls)# lsp tunnel1 device(config-router-mpls-lsp-tunnel1)# include-all gold silver
The following example includes administrative groups 4, 5, and 6.
device# configure device(config)# router mpls device(config-router-mpls)# bypass-lsp by-bypass-lsp device(config-router-mpls-bypass-lsp-by-bypass-lsp)# include-all 4 5 6
The following example includes administrative groups 4 and 5 on MPLS Ethernet interface 0/8.
device# configure device(config)# router mpls device(config-router-mpls)# mpls-interface ethernet 0/8 device(config-router-mpls-if-ethernet-0/8)# dynamic-bypass device(config-router-mpls-if-ethernet-0/8-dynamic-bypass)# include-all 4 5
