Hello Folks,

I shall be grateful to my fellow group members if you could suggest on
my
below rule of thumb commands (risk free exercises) which I want to apply
during my all lab practices.

1. no peer neighbor-route (Under BRI Interface)

2. no cdp enable (Under BRI Interface)

3. no auto-sum (RIP,EIGRP & BGP unless required)

4. no sync (BGP unless required)

5. ip ospf network point-to-point (for Loopback interface if advertised
in
ospf)

6. no ip split horizon (on the Hub router in Hub & spoke for EIGRP &
RIP)

7. no discard-route internal or external for summarization in OSPF ABR &
ASBR to eliminate NULL 0)

8. passive-interface default (RIP & EIGRP)

9. always hardcode the router-id for OSPF,EIGRP & BGP

10. ip ospf mtu-ignore for ospf adjacency on the peer router interface
of
CAT3550 (to avoid MTU Mismatch detection in DBD Packets)

Last but not least Iam looking for the best practices that I have to use
for
verification and testing when I complete each LAB.. as of now when I
complete the LAB I do my verification my pinging the loopback interface
of
all routers and reviewing the routing table but some times I found still
this exercise doesnt give full ip reachability and also I need to know
if
the reachability of routes generated by BB must always be reachable from
POD..? or are they any exceptions for BGP learned routes.

Please do let me know your suggestions and also pls. advise if you had
like
to add-on in this rules.

Thanks in advance,

Akbar khan
