This blog was originally started to better help me understand the technologies in the CCIE R&S blueprint; after completing the R&S track I have decided to transition the blog into a technology blog.

CCIE #29033

This blog will continue to include questions, troubleshooting scenarios, and references to existing and new technologies but will grow to include a variety of different platforms and technologies. Currently I have created over 185 questions/answers in regards to the CCIE R&S track!! Note: answers are in the comment field or within "Read More" section.

Troubleshooting 6

Here we go with another simple but interesting troubleshooting scenario


Ensure that R1 can ping R2 and ensure any optimizations are retained.  Interfaces are in an up/up state and there are no ACL or security features restricting access. Some configuration and debug outputs are included below. Please provide a working configuration.


R1
__

R1(config)#do ping 10.0.0.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.2, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)


interface Serial1/0
 ip address 10.0.0.1 255.255.255.0
 load-interval 30
 serial restart-delay 0
end


R2
__

R2#
