As stated in the previous chapter, MAGP configuration is required on the Spine switches when the fabric is utilizing L2 routing in the whole fabric. You can find more details about MAGP in the MAGP section of the UM.
To configure MAGP on the switches, you need to take the following steps on all spine switches used in your setup. In our use case we have one rack with two such switches:
Switch 1 Configuration
Create a VLAN interface.
switch (config)# interface vlan 20 switch (config interface vlan 20)#
Set an IP address to the VLAN interface.
switch (config interface vlan 20)# ip address 11.11.11.11 /8
Enable MAGP protocol globally.
switch (config)# protocol magp
Switch 2 Configuration
Create a VLAN interface:
switch (config)# interface vlan 20 switch (config interface vlan 20)#
Set an IP address to the VLAN interface.
switch (config interface vlan 20)# ip address 11.11.11.22 /8
Enable MAGP protocol globally.
switch (config)# protocol magp
Next steps (9-11) should be taken per VLAN (done for VLAN 10 below):Create a virtual router group for an IP interface.
switch (config interface vlan 20)# magp 10
Set a virtual router primary IP address.
switch (config interface vlan 20 magp 10)# ip virtual-router address 11.11.11.254
Set a virtual router primary MAC address.
switch (config interface vlan 20 magp 10)# ip virtual-router mac-address aa:bb:cc:dd:ee:ff
Verify the MAGP configuration.
switch (config)# show magp 10
The output in our setup will return the following:
MAGP 10 Interface vlan: 20 Admin state: Master State: Enabled Virtual IP: 11.11.11.254 Virtual MAC: aa:bb:cc:dd:ee:ff
