    交流tive-gateway

    Syntax

    交流tive-gateway {ip | ipv6} [] [mac]

    no active-gateway {ip | ipv6} [] [mac]

    Description

    Configures a virtual IP and virtual MAC for an interface VLAN

    Thenoform of this command removes the active gateway for active-active routing.

    Command context

    config-if-vlan

    Parameters

    ip

    指定一个IPv4地址的配置。

    ipv6

    Specifies the configuration of an IPv6 address.

    Specifies the IPv4 or IPv6 address.

    • Syntax for IPv4:A.B.C.D
    • Syntax for IPv6:A:B::C:D

    Specifies the Virtual MAC address. Syntax:xx:xx:xx:xx:xx:xx

    Authority

    Administrators or local user group members with execution rights for this command.

    Usage

    Before configuring active gateway, confirm that an IP address is on the SVI that is in the same subnet as the active gateway IP you are trying to configure. If an active gateway IP does not have an SVI IP with the same subnet, the CLI allows the configuration, but the active gateway IP will not be programmed in the kernel, resulting the active gateway to be unreachable.

    Active forwarding cannot be configured when ICMP redirect is enabled. Enter theno ip icmp redirectcommand for disabling ICMP redirect.

    It is highly recommended that you use an IPv6 link-local address as a gateway (VIP) on the active gateway IPv6 configuration.

    If VRRP or active forwarding is configured on an SVI, active gateway cannot be configured. Active gateway with overlapping networks is not allowed. Maximum of 16 unique virtual MACs are supported in a system.

    The maximum number of supported active gateways per switch is 4,000. Since a maximum of 31 secondary IPv4 addresses can be configured on an SVI, 32 IPv4 active gateways (along with the primary IPv4 address) can be configured per SVI with IP multinetting support. This support is also the same for IPv6 addresses.

    Do not use peer system MAC address as an active-gateway VMAC. If same MAC address is used, the VSX synchronization will try to sync the configuration on secondary switch and cause traffic disruptions.

    Examples

    Configuring active-gateway when the IP address is different from the SVI IP address on both VSX peers (valid for IPv6 and IPv4):

    Switch 1:

    switch1(config-if-vlan)#ip address 192.168.1.250/24switch1(config-if-vlan)#交流tive-gateway ip 192.168.1.253 mac 00:00:00:00:00:01switch1(config-if-vlan)#交流tive-gateway ipv6 fe80::01 mac 00:00:00:01:00:01

    Switch 2:

    switch2(config-if-vlan)#ip address 192.168.1.251/24switch2(config-if-vlan)#交流tive-gateway ip 192.168.1.253 mac 00:00:00:00:00:01switch2(config-if-vlan)#交流tive-gateway ipv6 fe80::01 mac 00:00:00:01:00:01

    Configuring active-gateway when the IP address is the same as the SVI IP address on both VSX peers (valid for IPv4 only):

    Switch 1:

    switch1(config-if-vlan)#ip address 192.168.1.250/24switch(config-if-vlan)#交流tive-gateway ip 192.168.1.250 mac 00:00:00:00:00:01

    Switch 2:

    switch2(config-if-vlan)#ip address 192.168.1.250/24switch2(config-if-vlan)#交流tive-gateway ip 192.168.1.250 mac 00:00:00:00:00:01

    Configuring only the active gateway address:

    switch(config-if-vlan)#ip address 192.168.1.250/24switch(config-if-vlan)#交流tive-gateway ip 192.168.1.250

    Configuring only the active gateway IP MAC address:

    switch2(config-if-vlan)#ip address 192.168.1.250/24switch2(config-if-vlan)#交流tive-gateway ip mac 00:00:00:01:00:01

    Removing the active gateway for active-active routing (IPv6 and IPv4):

    switch(config-if-vlan)#no active-gateway ipswitch(config-if-vlan)#no active-gateway ipv6

    Removing the active gateway for active-active routing for an IP address:

    switch(config-if-vlan)#no active-gateway ip 192.168.1.250

    Removing the active gateway for active-active routing for virtual MAC addresses:

    switch(config-if-vlan)#no active-gateway ip mac
