    Hi all,

     

     

    May i know whether MC-LAG support IPv6? If support is it the iccp ip still need IPv6 or just enough configure IPv4 only on ICCP?

     

     

    Thanks and appreciate any feedback

    Hi Kronicklez,

     

    Yes MC-LAG for IPv6 is supported on Junos 13.2 and higher, at least for QFX.  And ICCP config is IPv4 as usual, just need to configure the IRBs for IPv6 IP/VIP.

     

    For example: (just showing flexible-ethernet-tagging for example, the family on the LAG could be "ethernet-switching" as usual)

     

    root@Juniper# show interfaces ae0
    description "MCAE ID 1 Link ";
    enable;
    flexible-vlan-tagging;
    encapsulation flexible-ethernet-services;
    aggregated-ether-options {
    lacp {
    active;
    system-priority 100;
    system-id 00:00:00:00:00:01;
    admin-key 3;
    }
    mc-ae {
    mc-ae-id 1;
    redundancy-group 1;
    chassis-id 1;
    mode active-active;
    status-control standby;
    }
    }
    unit 0 {
    encapsulation vlan-bridge;
    vlan-id 1000;
    multi-chassis-protection 1.1.1.2 {
    interface xe-0/0/0.0;
    }
    }
    root@Juniper# show interfaces irb
    unit 0 {
    enable;
    family inet6 {
    address 2001::10/64 {
    vrrp-inet6-group 1 {
    virtual-inet6-address 2001::101;
    virtual-link-local-address fe80::101;
    accept-data;
    }
    }
    address fe80::10/64;
    address 2001::1:10/64;
    }
    }
     
    iccp {
    local-ip-addr 1.1.1.1;
    peer 1.1.1.2 {
    session-establishment-hold-time 60;
    liveness-detection {
    minimum-receive-interval 1000;
    transmit-interval {
    minimum-interval 1000;
    }
    }
    }

     

    Hope this helps.

    Hi Mriyaz,

     

     

    I'm look on this url https://www.juniper.net/documentation/en_US/junos/topics/concept/mc-lag-feature-concepts.html

     

    it has mention for IPv6 the MC-LAG support active-standby only right? Please correct me if i wrong .

     

     

    Thanks

    Hi Kroniclez,

     

    It depends on the platform, for QFX5100 (QFX5k mostly) it only supports active-active mode. 

     

    Hope this helps.

    Hi  kronicklez

     

    I hope you are doing great,

     

    I can confirm that you can configure it with IPV4 or IPV6 and should be fine.

     

    In these 500 pages MC-LAG guide:

     

    https://www.juniper.net/documentation/en_US/junos/information-products/pathway-pages/mc-lag/multichassis-link-aggregation-groups.pdf

     

    I found only these 2 major imports regarding IPV6, however take a look to it as it has many other IPV6/MC-LAG related things.

     

    Restrictions When Configuring MC-LAG Active-Active Bridge Domains In an IPv6 network, you cannot configure an MC-LAG in an active-active bridge domain if you specified the vlan-id none statement at the [edit bridge-domain bd-name] hierarchy level. The vlan-id none statement that enables the removal of the incoming VLAN tags identifying a Layer 2 logical interface when packets are sent over VPLS pseudowires is not supported for IPv6 packets in an MC-LAG.

     

    NOTE: You can configure IPv4 (inet) and IPv6 (inet6) addresses on mc-ae interfaces when the active-standby mode is configured.

     

     

    ***As mriyaz said active/active or active/standby depends of platform capabilities ***

     

    Warm regards!

    Hi kronicklez,

     

    yes, I can certainly tell that the QFX and EX series that support MC-LAG will support ipv6, VRRP groups for ipv4 and ipv6 can be used.

     

    just use the family inet6 for IRBs.

     

    Cheers,
