GRE Tunnel and Multicast Traffic

L0 Member

Hi Everyone,

 

Hi Team,

We have been trying to configure GRE tunnel. From the configuration end, everything seems fine and we have already followed the official KBs but GRE tunnel nevers gets up. And this is affecting our multicast traffic flow. Same thing works fine from one of our Lab Firewall, GRE tunnel gets up and we can ping the client's end tunnel interface IP.

So, we don't think there's any issue in the client's end. We can reach client with different firewall but only the issue is seen with PaloAlto Firewall.

 

Note: I have raised the ticket in TAC support but they are still unable to track the issue. They are just wasting my time.

 

Please do not suggest me these KBs as i have followed this several time:
