Jayapal Reddy commented on CLOUDSTACK-7544:
-------------------------------------------
Problem:
-----------
first ip address on additional public subnet is deleted observed that the
interface on the router removed
Root Cause Analysis:
--------------------------
1. deleting primary ip deletes all the ips on the interface
2. Here deleting 10.147.48.90 deletes the other ip.
root@r-2-VM:~# ip addr show dev eth4
24: eth4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP
qlen 1000
link/ether 06:cb:fa:00:00:0d brd ff:ff:ff:ff:ff:ff
inet 10.147.48.90/24 scope global eth4
inet 10.147.48.92/24 scope global secondary eth4
inet6 fe80::4cb:faff:fe00:d/64 scope link
valid_lft forever preferred_lft forever
root@r-2-VM:~# ip addr del dev eth4 10.147.48.90/24
root@r-2-VM:~# ip addr show dev eth4
24: eth4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP
qlen 1000
link/ether 06:cb:fa:00:00:0d brd ff:ff:ff:ff:ff:ff
inet6 fe80::4cb:faff:fe00:d/64 scope link
valid_lft forever preferred_lft forever
Proposed solution:
-----------------------
After deleting the ip add the remaining ips again into interface.
Verification steps:
----------------------
1. Create additional public subnet
2. Acquire more than ip and configure some rules on the ip.
3. Delete the first ip and make sure remaining ips are present on the interface.
> In multiple public subnet interface all ips got removed while removing first
