Sting Matching in Shell script

Sting Matching in Shell script

I am trying to match two strings (IpAddress) as below. But its not matching.
i=192.168.2.29
ipCheckInConfig="SG_1=192.168.2.24,192.168.2.29
> SG_2=192.168.2.20,192.168.2.23,192.168.2.31"
if echo "$i" | egrep -q "$ipCheckInConfig" ; then
echo "Matched"
else
echo "Not Matched"
fi
Could someone please help?
