vsr running config# vrf <vrf> routing isis instance <string> segment-routing
vsr running segment-routing# enabled true|false
- Default value
false
label-blocks¶
Set local and global label blocks.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing label-blocks
srgb¶
Set global blocks to be advertised.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing label-blocks srgb
lower-bound¶
Set lower value in the label range.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing label-blocks srgb
vsr running srgb# lower-bound <16-1048575>
- Default value
16000
upper-bound¶
Set upper value in the label range.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing label-blocks srgb
vsr running srgb# upper-bound <16-1048575>
- Default value
23999
srlb¶
Set local blocks to be advertised.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing label-blocks srlb
lower-bound¶
Set lower value in the label range.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing label-blocks srlb
vsr running srlb# lower-bound <16-1048575>
- Default value
15000
upper-bound¶
Set upper value in the label range.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing label-blocks srlb
vsr running srlb# upper-bound <16-1048575>
- Default value
15999
msd¶
Set maximum segment depth identifiers (MSD) configuration.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing msd
node-msd¶
Set maximum number of label that can be stack.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing msd
vsr running msd# node-msd <1-16>
ipv6¶
Configure IS-IS SRv6 (Segment routing IPv6).
vsr running config# vrf <vrf> routing isis instance <string> segment-routing ipv6
locator (mandatory)¶
Configure a SRv6 locator. A locator is the first part of a SID that consists of the most significant bits representing the address of a particular SRv6 node. The locator is very similar to a network address that provides a route to its parent node. The locator is further subdivided into a SID block and a node ID. The locator length should be 64-bits long.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing ipv6
vsr running ipv6# locator <string>{1,255}
prefix-sid-map¶
Set list of prefix SID mapped to IPv4/IPv6 local prefixes.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing prefix-sid-map <prefix-sid-map>
|
Description |
|---|---|
|
The ipv4-prefix type represents an IPv4 address prefix. The prefix length is given by the number following the slash character and must be less than or equal to 32. A prefix length value of n corresponds to an IP address mask that has n contiguous 1-bits from the most significant bit (MSB) and all other bits set to 0. The canonical format of an IPv4 prefix has all bits of the IPv4 address set to zero that are not part of the IPv4 prefix. |
|
The ipv6-prefix type represents an IPv6 address prefix. The prefix length is given by the number following the slash character and must be less than or equal to 128. A prefix length value of n corresponds to an IP address mask that has n contiguous 1-bits from the most significant bit (MSB) and all other bits set to 0. The IPv6 address should have all bits that do not belong to the prefix set to zero. The canonical format of an IPv6 prefix has all bits of the IPv6 address set to zero that are not part of the IPv6 prefix. Furthermore, the IPv6 address is represented as defined in Section 4 of RFC 5952. |
sid-value-type¶
This leaf defines how value must be interpreted.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing prefix-sid-map <prefix-sid-map>
vsr running prefix-sid-map <prefix-sid-map># sid-value-type SID-VALUE-TYPE
|
Description |
|---|---|
|
The value will be interpreted as an index. |
|
The value will become interpreted as an absolute value. |
- Default value
index
sid-value (mandatory)¶
Set value associated with prefix. The value must be interpreted in the context of sid-value-type.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing prefix-sid-map <prefix-sid-map>
vsr running prefix-sid-map <prefix-sid-map># sid-value <uint32>
last-hop-behavior¶
Configure last hop behavior.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing prefix-sid-map <prefix-sid-map>
vsr running prefix-sid-map <prefix-sid-map># last-hop-behavior LAST-HOP-BEHAVIOR
|
Description |
|---|---|
|
Use explicit-null for the SID. |
|
Do not use Penultimate Hop Popping (PHP) for the SID. |
n-flag-clear¶
Set this flag if this node is not a node SID.
vsr running config# vrf <vrf> routing isis instance <string> segment-routing prefix-sid-map <prefix-sid-map>
vsr running prefix-sid-map <prefix-sid-map># n-flag-clear true|false
- Default value
false
