Configuring CCC Switching for Point-to-Multipoint LSPs
You can configure circuit cross-connect (CCC) between two circuits to switch traffic from interfaces to point-to-multipoint LSPs. This feature is useful for handling multicast or broadcast traffic (for example, a digital video stream).
To configure CCC switching for point-to-multipoint LSPs, you do the following:
- On the ingress provider edge (PE) router, you configure CCC to switch traffic from an incoming interface to a point-to-multipoint LSP.
- On the egress PE, you configure CCC to switch traffic from an incoming point-to-multipoint LSP to an outgoing interface.
The CCC connection for point-to-multipoint LSPs is unidirectional.
For more information about point-to-multipoint LSPs, see Point-to-Multipoint LSPs Overview.
To configure a CCC connection for a point-to-multipoint LSP, complete the steps in the following sections:
Configuring the Point-to-Multipoint LSP Switch on Ingress PE Routers
To configure the ingress PE router with a CCC switch for a point-to-multipoint LSP, include the p2mp-transmit-switch statement:
You can include the p2mp-transmit-switch statement at the following hierarchy levels:
- [edit protocols connections]
- [edit logical-systems logical-system-name protocols connections]
switch-name specifies the name of the ingress CCC switch.
input-interface input-interface-name.unit-number specifies the name of the ingress interface.
transmit-p2mp-lsp transmitting-lsp specifies the name of the transmitting point-to-multipoint LSP.
Configuring Local Receivers on a Point-to-Multipoint CCC LSP Switch on Ingress PE Routers
In addition to configuring an incoming CCC interface to a point-to-multipoint LSP on an ingress PE router, you can also configure CCC to switch traffic on an incoming CCC interface to one or more outgoing CCC interfaces by configuring output interfaces as local receivers.
To configure output interfaces, include the output-interface statement at the [edit protocols connections p2mp-transmit-switch p2mp-transmit-switch-name] hierarchy level.
You can configure one or more output interfaces as local receivers on the ingress PE router using this statement.
Use the show connections p2mp-transmit-switch (extensive | history | status), show route ccc <interface-name> (detail | extensive), and show route forwarding-table ccc <interface-name> (detail | extensive) commands to view details of the local receiving interfaces on the ingress PE router.
Configuring the Point-to-Multipoint LSP Switch on Egress PE Routers
To configure the CCC switch for a point-to-multipoint LSP on the egress PE router, include the p2mp-receive-switch statement.
You can include this statement at the following hierarchy levels:
- [edit protocols connections]
- [edit logical-systems logical-system-name protocols connections]
switch-name specifies the name of the egress CCC switch.
output-interface [ output-interface-name.unit-number ] specifies the name of one or more egress interfaces.
receive-p2mp-lsp receptive-lsp specifies the name of the receptive point-to-multipoint LSP.
