Knowledge of nine Cisco Routers

Cisco router knowledge has become more and more widely used in modern enterprises. Next we will briefly learn about the secure router configuration solution.

Knowledge of nine Cisco routers required by network engineers

1. Are the routing protocols supported by Cisco routers compatible with those of other manufacturers?

In addition to IGRP and VPN, one of the Cisco routers is that all the routing protocols supported are compatible with the same protocols implemented by other manufacturers. IGRP and VPN are Cisco's patented products.

2. What are the descriptions of table items in the RIP route table?

Each table item in the RIP route table provides certain information, including the destination address, the next hop address to the destination, and the measurement value. This metric value indicates the distance to the target terminal (number of hops ). Other information can also be included.

3. Does Cisco3600 series router currently Support WAN Interface Card WIC-2T and WIC-2A/S?

Cisco3600 series routers support both WIC-2T and WIC-2A/S wan interface cards in 12.007XK and later versions.
However, note the following:
Only the Fast Ethernet hybrid network module can support these two wan interface cards.
The network modules supporting these two interface cards are as follows:
NM-1FE2W, NM-2FE2W, NM-1FE1R2W, NM-2W.
The Ethernet hybrid network module does not support the following features:
NM-1E2W, NM-2E2W, NM1E1R2W.

4. What is the maximum rate of synchronization supported by Cisco3600 series routers (4A/S, NM (8A/S network module and WIC (2A/s wan Interface Card?

These Cisco router knowledge tells us that the network module and WAN Interface Card support both asynchronous and synchronous. The maximum asynchronous rate supported is 115.2 Kbps, and the maximum synchronous rate is 128 Kbps.

5, WIC-2T and WIC-1T cable is what kind?

WIC-1T: DB60 to V35 or RS232, 449 and other cables. Such as: CAB-V35-MT.
WIC-2T: SMART type to V35 or RS232, 449 and other cables. Such as: CAB-SS-V35-MT.

6. What is the difference between MCE1 in the Cisco 7000 Series and E1 and CE1 in Cisco 2600/3600?

MCE1 on Cisco 7000 can be configured as E1 and CE1, while E1 and CE1 on Cisco 2600/3600 only support their own functions.

7. Does a Cisco 2600 series router support inter-VLAN routing? What are the requirements for IOS software?

In Cisco (2600 series routers, only Cisco2620 and Cisco2621 support inter-VLAN routing (MB ports support inter-VLAN Routing ). If Inter-VLAN routing is supported, IOS software must include the IP Plus feature set.

8. What are the differences in hardware between the Cisco3660 router and the 3620/3640 router?

Cisco router knowledge: Understand their differences:
* The basic configuration of the Cisco3660 router includes one or two 10/100 M Adaptive Fast Ethernet interfaces. The basic configuration of Cisco3620/3640 does not include Ethernet interfaces.
* Cisco3660 vro supports hot swapping of network modules, while Cisco3620/3640 does not support hot swapping of network modules.
* The Cisco3660 redundant power supply is built in, while the Cisco3620/3640 redundant power supply is external.

9. What types of access tables are supported?

The number of an access table can be determined. The specific protocol and its corresponding access table number are as follows:
◎ I P standard Access Table No.: 1 ~ 9 9
◎ I P extended access table No.: 1 0 0 ~ 1 9 9
◎ I P X standard Access Table No.: 8 0 0 ~ 8 9 9
◎ I P X extended access table No.: 1 0 0 0 ~ 1 0 9 9
◎ AppleTa l k Access Table No.: 6 0 0 ~ 6 9 9
Note: In Cisco IOS Release11.2 or later versions, you can use the famous access table to determine the number between 1 and later ~ 199 access table.
