The minimum value is the IPv6 minimum MTU value. The maximum value is set to the FP4 maximum Ethernet port MTU (9800) minus 14 bytes for Null Ethernet encapsulation.

type keyword

Synopsis

SRv6 FPE application type

Tree
Description

This command specifies if the SRv6 FPE application is used for origination or termination of SRv6 tunnels. 

A dedicated SRv6 FPE is required for origination and termination of SRv6 tunnels on services and they cannot share the same FPE. 

A single FPE can be configured for SRv6 origination. One or more FPEs can be configured for SRv6 termination, where a termination SRv6 FPE is assigned one or more configured locators. 

Transit SRv6 routers do not require SRv6 FPEs.

Options

origination, termination

sub-mgmt-extension boolean

Synopsis

Enable FPE for subscrber management extensions

Description

When configured to true, the FPE is used for subscriber management extensions. The FPE can be used for multiple subscriber management applications, but it cannot be used for other applications.

When configured to false, the FPE is not used for subscriber management extensions. 

Default

false

sdp-id-range

Synopsis

Enable the sdp-id-range context

Description

Commands in this context configure the SDP ID range used by the FPE based PW port and VXLAN termination applications.

Each configured FPE-based PW port is associated with two internal SDPs (one in each direction) whose IDs are allocated from the configured SDP ID range. When the FPE is associated with VXLAN termination, an internal SDP is allocated from the configured SDP ID range and is used for R-VPLS services that terminate VXLAN IPv6. A spoke SDP per VXLAN IPv6 R-VPLS service is created on that SDP for egress processing of the packets. The SDP ID range cannot be modified if any of its IDs are currently in use.
