Can use RegEx to compare two captured groups

Question

I have a log message that i want to match only if two captured groups are the same! example

some date from source-ip=1.1.1.1 trying to send another data to the destination-ip=1.1.1.1 in addition to some date

So, i want to trigger if sip=dip it matches!? Would it be possible using a single regex?

Using "some date from source-ip=1.1.1.1 trying to send another data to the destination-ip=1.1.1.1 in addition to some date" as input:

(\d+\.\d+\.\d+\.\d+).*(\1)
