Comprehensive GNS3 knowledge training experiment

Use R3 to set the ip default-network 5.0.0.0 as the default gateway for R1 and R2 to access the Internet 111.111.111.111.
View the Management Distance and latency of the v5.0.0.0 routes by using show ip VPN to all, compare the AD/FD, calculate the va value, and set the v5.0.0 route to all.
In order to simulate non-overhead load balancing, the bandwidth and latency of the inbound interface of R2 are extended, and the bandwidth and latency of the inbound interface of R1 are reduced.
