3.3.h Implement optimize and troubleshoot redistribution between any routing protocol,

are great practice… and a great resource… and he has hundreds…

he has some nice thoughts with this one… i have a tendency to use network statements for everything… this is faster:

Rodman(config-router)#do sh run | b router
router ospf 1
log-adjacency-changes
network 0.0.0.0 255.255.255.255 area 0
!
router bgp 1
no synchronization
bgp log-neighbor-changes
redistribute ospf 1
neighbor 2.2.2.2 remote-as 1
neighbor 2.2.2.2 update-source Loopback0
neighbor 3.3.3.3 remote-as 1
neighbor 3.3.3.3 update-source Loopback0
no auto-summary

of course you have to put up with the question marks, which isn’t pretty… but it saves on the typing…

6.1.b Implement and troubleshoot SNMP

same but different… simply put, rmon is for flow monitoring, snmp is for device management…

according to wiki:

In short, RMON is designed for “flow-based” monitoring, while SNMP is often used for “device-based” management. RMON is similar to other flow-based monitoring technologies such as NetFlow and SFlow because the data collected deals mainly with traffic patterns rather than the status of individual devices. One disadvantage of this system is that remote devices shoulder more of the management burden, and require more resources to do so. Some devices balance this trade-off by implementing only a subset of the RMON MIB groups. A minimal RMON agent implementation could support only statistics, history, alarm, and event.
