5.3 EIGRP Timer

The task was to make eigrp warn about neighbor down half the default time.
That means hold-time of 7.5 s, but don't forget to change the hello time because the default 5s can cause instability.

Important things : in eigrp, hold-time could be different on each side because waht we configure on R1 for example means "Hello i'm R1, if you neighbor don't hear about me in X seconds i'm dead'

In ospf timers should be the same and changing hello will automatically change dead-time to x4


6.1 OSPF Loopback

Bonehead error : Forgot about what the guidelines asked " the prefix should apperas in RIB with original mask". I dumbly advertised loopback being /32 :
- change the ip ospf network type of lo0
- redistribute connected
- put lo0 on another area and summarize to the regular mask.

7.3 BGP Prefix length route filtering

The task was about filtering all prefixes having /24 or more prefix.
I've done the more but let go the /24 itself. As all routes were /24 I missed the point to find a way of summarize to /23 to let them enter !!

8.1 Time to wait before timeout a output telnet session

Play with syn timeout :

ip tcp synwait-time 5

8.2 default NTP stratum

Is 8 not 16. So 2 less than the default is 6. stupid error.

10.2 Policing on subinterface

MQC policing on subinterface is permitted. The other way the design guide choose is too apply on interface and match the subinterface vlan.

A simple recall it's queueing techniques that are not allowed on subinterace (LLQ and CBWFQ). To make this works you need to apply shaping on a default-class and nest a LLQ OR CBWF policy-map on it

11.3 Rate-limit Mcast

I configured it with mqc. Can also use ip multicast rate-limit
