Calculating Burst

According to the Doc CD:

norm-burst = cir / 8 (to convert to bytes) * 1.5
max-burst = cir / 8 (to convert to bytes) * 2

Frame Relay End-to-End Keepalives

Polling the other side of the VC can be done through the use of the map-class.

4 Ways to Derive L3-to-L2 Mappings in Frame Relay

WRED in MQC Conditions

In order to configure WRED in MQC, one of two conditions must exit:

1. There must be a bandwidth reservation statement within a class

OR

2. The default-class must be running weighted fair queueing


Consequently, you may have to use the match not command to isolate the traffic you want (match not protocol ftp - move it to NON_ClassDefault and then FTP will be only thing remaining in class-default) and then enable fair-queue and random-detect in class-default.

4 Ways to Originate BGP Prefixes

There are four ways to originate BGP prefixes:

1. Redistribute static route
2. Network command
3. Aggregate-address command
4. Inject-map

Methods of Filtering Updates

Any of the following methods will allow you to filter routes:

3. Distance command

Stub Breakdown

Stub Area Gotcha

When configuring the stub area, don't forget to watch out for Loopbacks that were redistributed via connected w/ route-map. If you accidentally configure it as a stub area instead of NSSA, you will lose that route from the domain.

Extended VLANs Reminder

When you are using VTP transparent mode, the VLAN configuration is stored in the running-config/startup-config, instead of in vlan.dat file. The extended VLANs (1006-4094) can be trunked through VTP server and client switches, but no ports can become members of these vlans.
