Mlag default route

[Edward]

Hi,

I have an question with mlag which my access switch default route should point to which Core Switch? Please refer to below scenario.

Core Switch 1
=========================================
Create vlan test10 tag 10
Configure test10 ipaddress 192.168.10.1/24
configure test10 add port 23, 24 tagged
Create vlan test20 tag 20
Configure test20 ipaddress 192.168.20.1/24
configure test20 add port 23, 24 tagged
configure default ipaddress 192.168.1.1/24
enable ipforwarding

Create vlan isc tag 3000
configure isc ipaddress 1.1.1.1/24
configure isc add port 24 tagged

Create mlag peer "peerToCS2"
config mlag peer "peertoCS2" ipaddress 1.1.1.2
enable mlag port 23 peer "peerToCS2" id 1

Core Switch 2
=========================================
Create vlan test10 tag 10
Configure test10 ipaddress 192.168.10.1/24
configure test10 add port 23, 24 tagged
Create vlan test20 tag 20
Configure test20 ipaddress 192.168.20.1/24
configure test20 add port 23, 24 tagged
configure default ipaddress 192.168.1.2/24
enable ipforwarding

Create vlan isc tag 3000
configure isc ipaddress 1.1.1.2/24
configure isc add port 24 tagged

Create mlag peer "peerToCS1"
config mlag peer "peertoCS1" ipaddress 1.1.1.1
enable mlag port 23 peer "peerToCS1" id 1

Access Switch
==========================================
Create vlan test10 tag 10
configure test10 add port 21 tagged
Create vlan test20 tag 20
configure test20 add port 21 tagged
enable sharing 23 grouping 23-24

configure default ipaddress 192.168.1.4/24
configure iproute add default 192.168.1.x ????

Thanks and Regards,
Edward

We have already discussed acitve-active VRRP with MLAG in above post. still, if you have any doubt then let us know.

Hello Edward Sumit is right what you need to do is set up VRRP and specifically active/active setting which is explained on page 1118 of the 15.4 ExtremeXOS concepts guide.

This will allow both MLAG switches to act as the default gateway.

Let us know if you have questions after reading it.

Thanks, I will look into vrrp set up.

[Sumit_Tokle]

I believe you can configure the VRRP on core 1 and core 2 switch and configure VIP as default gateway on ACCESS switch.

VRRP would be the best solution to allow for the traffic to really span to both core switches.
