Network Design for a Dial NMS Case Study

Configuration Design Parameters

Table 7	IP Subnetting Plan for POP #1 and POP #2

Network Name		Assigned IP Subnet		Description

POP #1		172.21.0.0/16		Class B IP subnet assigned to POP #1.

POP #2		172.22.0.0/16		Class B IP subnet assigned to POP #2.

NOC		172.23.10.0/24		Class C IP subnet assigned to the NOC.

Access		172.21.101.0/24		Primary and secondary class C access Ethernet subnets.
		172.21.102.0/24		All the access devices in each POP are directly connected
		172.22.101.0/24		to these subnets.
		172.22.101.0/24
		172.22.102.0/24

DeviceID		172.21.10.0/24		Identifies each Cisco IOS device with a unique, fixed, and
		172.22.10.0/24		stable loopback IP address for network management
				purposes.
				One IP address is assigned to the loopback 0 interface of
				each Cisco IOS device.
				One IP address block is used to simplify IP-security
				filtering at the NOC. This technique protects the NOC
				from devices that should not access management
				services, such as TACACS+, RADIUS, syslog, and
				SNMP.

IP pool		172.21.103.0/24		Hosts a pool of IP addresses for the dial access clients
		172.21.104.0/22		with modems.
		172.22.103.0/24		This IP assignment provides 1280 IP addresses to each
		172.22.104.0/22		POP. The access servers create the IP routes to support
				the IP pools.
				Few IP routes are summarized to the backbone instead of
				advertising 1280 host routes.

Table 8	SNMP Community Strings Used at THEnet

Community Strings			Purpose

5urf5h0p			Assigns a read-only (RO) community string to enable SNMP polling and
			SNMP get requests.

5crapmeta1			Assigns a read-write (RW) community string to enable router configuration
			changes.

Caution Do not use “public” or “private” strings, which are well known in the industry, are common hardware defaults, and invite attacks from hackers—regardless if you use filters. To maximize security, choose community strings that are not associated with your personal life or company.
