From 98c2c5e0585e0806099a353de207f392223eff9a Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Sat, 22 Aug 2020 23:15:29 +0200 Subject: dhcpv6-pd: T2677: optimize CLI interface for PD configuration The current CLI did not support multiple prefix-delegations per interface. Some ISPs only send one /64 to a client per prefix-delegation request, but they allow the customer to request multiple prefixes. The 'dhcpv6-options prefix-delegation' node has been renamed and converted to a tag node named 'dhcpv6-options pd'. The tag node specifies a PD request (>=0). In the past the user needed to know what prefix will be assigned and required to calculate the sla-len by himself. The 'sla-len' node was dropped and is now calculated in the background from the 'dhcpv6-options pd 0 length' node. It is no longer mandatory to supply the 'sla-id' node, if sla-id is not specified it is 'guessed' by counting upwards. Example configuration: ---------------------- ethernet eth1 { address dhcpv6 dhcpv6-options { pd 0 { length 56 interface eth2 { address 1 } } } } This will request a /56 assignment from the ISP and will delegate a /64 network to interface eth2. VyOS will use the interface address ::1 on the delegate interface (eth2) as its local address. --- src/conf_mode/interfaces-pppoe.py | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'src/conf_mode') diff --git a/src/conf_mode/interfaces-pppoe.py b/src/conf_mode/interfaces-pppoe.py index 928113b49..901ea769c 100755 --- a/src/conf_mode/interfaces-pppoe.py +++ b/src/conf_mode/interfaces-pppoe.py @@ -15,7 +15,6 @@ # along with this program.
