IST VLAN IP 1.1.1.1
« on: November 13, 2018, 04:10:09 AM »
Hello! I have 2 ERS-8600 and IST-VLAN 3999, with IP 1.1.1.1 and 1.1.1.2 mask 255.255.255.252.
But now we want to use cloudflare DNS with address 1.1.1.1.
How I can change IST-VLAN interface ip address to another, may be 192.168.100.1 and 192.168.100.2 without any problem?
If I try simply change IP in this vlan - Will I get any serious problems?

Hi dimitry-nov,

you'll need to disable the IST-Cluster-Connect to change the IST-Vlan IP-Addressing.
For that you should disable all SMLT/MLT-Links on one of the IST-Members, then disable IST on both IST-Members , change IST-Vlan IP Addressing on both IST-Members, re-enable IST on both IST-Members.
Finally enable previous disabled redundant links on the chassis.

Good luck
