Configuring CCC Switching for Point-to-Multipoint LSPs
You can configure CCC 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 on 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 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 or one or more egress interfaces.
receive-p2mp-lsp receptive-lsp specifies the name of the receptive point-to-multipoint LSP.
