findif.sh: fix to avoid duplicate route issues

[vdevik-nok]

Hi,
The following is the rpm versions used in the ha setup.

resource-agents-4.10.0-71.el9_6.11.x86_64
pacemaker-2.1.9-1.2.el9_6.x86_64
corosync-3.1.9-2.el9_6.x86_64

We are observing the following error and the resource vip_ipv6 is not getting started.

pcs resource config vip_ipv6

Resource: vip_ipv6 (class=ocf provider=heartbeat type=IPaddr2)
Attributes: vip_ipv6-instance_attributes
cidr_netmask=112

interval=10s
start: vip_ipv6-start-interval-0s

The same issue is reported here https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1109925 and mentioned that the fix is available in resource-agents_4.16.0-4.debian.tar.xz.

But similar version of the rpm is not available at https://rockylinux.pkgs.org/9/rockylinux-highavailability-x86_64/.
Can you please let us know if there is fix rpm available for el9 and from where it can be downloaded.

The fix was added in 9.7.
