Release Information Statement introduced in Junos OS Release 9.2.
Statement introduced in Junos OS Release 12.2 for ACX Series routers.
Statement introduced in Junos OS Release 12.3 at the [edit protocols l2circuit
local-switching interface interface-name] hierarchy level.
Description Configure pseudowire redundancy for Layer 2 circuits and VPLS. A redundant pseudowire
can act as a backup connection and can be configured between a PE router and a CE
device or between PE routers, maintaining Layer 2 circuit and VPLS services after certain
types of failures. This feature can help improve the reliability of certain types of networks
where a single point of failure could interrupt service for customers.
NOTE: VPLS is not supported on ACX Series routers. The psn-tunnel-endpoint
statement is not supported at the [edit protocols l2circuit local-switching
interface interface-name end-interface interface interface-name] hierarchy level.
Options address—Specifies the address for the backup neighbor.
The remaining statements are explained separately. See CLI Explorer.
Required Privilege
Level
routing—To view this statement in the configuration.
