Tables

IPv6SegmentRoutingHeader.new_args

Constructor arguments

Fields:

• segmentleft num the number of segments left
• hmackey num the hmac key index
• cflag num the Cleanup flag
• pflag num the Protected flag
• segments table See setsegments
• policies table See setpolicies
• hmac table See sethmac

Methods

IPv6SegmentRoutingHeader:setsegments (segments)

Set the segment list

Parameters:

• segments table a list IPv6Addresses (strings)

Usage:

 srh:setsegments{
   '2001:db8:1234::1',
   '2001:db8:5678::1',
   '2001:db8:9abc::1'
 }

IPv6SegmentRoutingHeader:setpolicies (segments)

Set the policy list

Parameters:

• segments table a list of pairs {type=num, value=string} for all 4 policies

Usage:

 srh:setpolicies{
   {type=IPv6SegmentRoutingHeader.policy_destination, value='2001:db8::1'},
   {type=IPv6SegmentRoutingHeader.policy_source, value='2001:db8::2'},
 }

IPv6SegmentRoutingHeader:sethmac (hmac)

Set the HMAC field

Parameters:

• hmac table a list of at most 32 bytes for the HMAC value, 0-padded

Usage:

srh:sethmac{0x1, 0x2, 0x3, 0x4, ...}

IPv6SegmentRoutingHeader:new ([args])

Constructor for an IPv6SegmentRoutingHeader Layer

Parameters:

• args table arguments, all grouped inside a table, see new_args (optional)

Returns:

IPv6SegmentRoutingHeader a new IPv6SegmentRoutingHeader object

Usage:

 IPv6SegmentRoutingHeader.new{
   segmentleft=3,
   cflag=1,
   segments={ '2001:db8::1', '2001:db8::2' },
   hmackey=4,
   hmac={ 0xe, 0xa, 0x12 } -- will be 0-padded
 }

IPv6SegmentRoutingHeader:segmentleft ()

Set the number of segment left to be processed in the segment list

IPv6SegmentRoutingHeader:cflag ()

Set the cleanup flag

IPv6SegmentRoutingHeader:pflag ()

Set the protected flag

IPv6SegmentRoutingHeader:hmackey ()

Set the hmac key
