Configured ospf over GRE tunnel in which packets are double tagged with ip header, useful when there is no direct connection between the 2 routers but still we need to run ospf.
NHRP_registration.cap (648 bytes)
| Packets: 4 | Duration: n/a | Downloads: 3271 |
R2 registers a multipoint GRE tunnel with R1. Capture perspective from the R1-R5 link.
mGRE_ICMP.cap (3.7 KB)
| Packets: 24 | Duration: 10s | Downloads: 4267 |
R2 begins sending ICMP traffic to R4, but it currently only has a GRE tunnel open to R1. The first two ICMP requests (packets #1 and #4) are routed through R1 while R2 sends an NHRP request to R1 for R4's spoke address. Once a GRE tunnel is dynamically built between spoke routers R2 and R4, R2 begins routing the ICMP traffic directly to R4. Capture perspective from the R2-R5 link.
