========
We need to ping from R1 (RED vrf ) to R3 (BLUE vrf).
R1-RED-----------------RED--R2--BLUE------------------BLUE--R3
1.1.1.1 1.1.1.2 2.2.2.1 2.2.2.2
101#ping vrf RED 2.2.2.2 ------------à pinging vrf BLUE’s 2.2.2.2 from R1’s VRF RED.
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
