NAME

ip-sr - IPv6 Segment Routing management  

SYNOPSIS

ip sr { COMMAND | help }

ip sr hmac show

ip sr hmac set KEYID ALGO

ip sr tunsrc show

ip sr tunsrc set ADDRESS

 

DESCRIPTION

The ip sr command is used to configure IPv6 Segment Routing (SRv6) internal parameters.

Those parameters include the mapping between an HMAC key ID and its associated hashing algorithm and secret, and the IPv6 address to use as source for encapsulated packets.

The ip sr hmac set command prompts for a passphrase that will be used as the HMAC secret for the corresponding key ID. A blank passphrase removes the mapping. The currently supported algorithms for ALGO are sha1 and sha256.

If the tunnel source is set to the address :: (which is the default), then an address of the egress interface will be selected. As this operation may hinder performances, it is recommended to set a non-default address.

 

EXAMPLES

 

Configure an HMAC mapping for key ID 42 and hashing algorithm SHA-256

# ip sr hmac set 42 sha256

 

Set the tunnel source address to 2001:db8::1

# ip sr tunsrc set 2001:db8::1
