"ip address"/"ip unnumbered" for Tunnel interface
I have a following tunnel interface configuration:
Am I correct that IP address 8.8.8.8 is used as a source IP address in the GRE encapsulated IP header only in case the packet is originated from the C1841 router itself?
C1841#sh run int tu0 Building configuration... Current configuration : 153 bytes ! interface Tunnel0 ip address 8.8.8.8 255.255.255.0 keepalive 5 3 tunnel source FastEthernet0/0 tunnel destination 10.10.10.1 tunnel checksum end C1841#
Am I correct that IP address 8.8.8.8 is used as a source IP address in the GRE encapsulated IP header only in case the packet is originated from the C1841 router itself?

I would assume so (unless you're doing NAT/PAT of course)
How does ip unnumbered enter into this?
