Configure OSPF on X670-G2

  • 1.  Configure OSPF on X670-G2

    Hi all
    I have to configure OSPF and VRRP in an hospital networks, we have two X670-G2 with Core license. My requirement is have high availability for vlan default gateway and for distribuiting static routes on OSPF.

    Below my hospital network



    Our requirements are: have GW HA for each Vlan, and DR and BDR that redistribute the same connected networks and static routes.

    My needs is, have a network fault tollerant when DR fails.

    ####sample configuration for one vlan

    Core-1

    Vlan 3 Mngt
    configure vlan Mngt ipaddress 192.168.10.50/24
    enable ipforwarding vlan Mngt

    create vrrp vlan Mngt vrid 1
    configure vrrp vlan Mngt vrid 1 priority 255
    configure vrrp vlan Mngt vrid 1 add 192.168.10.1
    configure vrrp vlan Mngt vrid 1 preempt delay 60
    enable vrrp vlan Mngt vrid 1
    sh vrrp

    Core-2

    Vlan 3 Mngt
    configure vlan Mngt ipaddress 192.168.10.51/24
    enable ipforwarding vlan Mngt

    create vrrp vlan Mngt vrid 1
    configure vrrp vlan Mngt vrid 1 add 192.168.10.1
    enable vrrp vlan Mngt vrid 1
    sh vrrp

    ####OSPF configuration
    Core-1

    enable ospf export static cost

    Hi it might be to late but why not look at stacking the two core switches?? This will simplify your config with no need for vrrp/stp/mlag etc. A single HA core

    We are using MLAG for connecting access switches and VRRP. We had excluded stacking the two X670-G2 because in case of XOS upgrade, we can do this switch by switch, without network downtime.
    We had stacked only switch distributor or access.

    Hi, to redistribute static routes into OSPF, you will need to write an ACL to call for static routes that are advertised in the "export" command. The following article gives you the steps -
