2001:1::1 The MPLS Domain consists of three routers: PE1 , P , and PE2 . The IGP protocol running in the domain is OSPF , and the process ID is 100 . Each of the three routers announces its own loopback port into Core 's OSPF . The address of Loopback is xxxx/32 , and x is the router number, such as PE1 is 2.2.2.2 , P is 3.3.3.3 , and PE2 is 4.4.4.4 . For configuration, here's a simple example: The configuration of R3 is as follows (basic configuration): Ipv6 enable IPv6 Header Routing time: The time elapsed since the last time the routing entry was modified. The routing time is reset to 0 each time the routing entry is modified . # 38.25.63.10 Modified OSPF the AD value ! Ip address 10.1.12.1 255.255.255.0 Load distribution: 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 (refcount 1) A specified 32bits of Router-ID ALG and IPV4 single protocol network host B maintain an IPV4 session. ALG is responsible for session conversion between IPV4 and IPV6 . This ALG has dual stack support capabilities. For example, suppose ALG is a dual stack and can act as a server for SMTP ALG . Then A can be based on IPV6 of Ipv6 nat R2(config-router)# redistribute eigrp 100 subnets Router(config-router)# Prefix list configuration In CISCO IOS , CEF can hash the source and destination IP addresses and import the hashed results into a load balancing table for load balancing. This table has 16 hash buckets , each of which points to an adjacency,ccna practice test pdf, and multiple buckets can point to an adjacency at the same time. You can use the show ip cef route prefix internal hidden command to see: RIP based on rumor updates The IPv6 address that the node must have : 850 Ipv6 dhcp pool DHCP-pool OSPF redistributed directly connected interface default cost20 ; redistributed static route default cost20 ; using the default-metric can modify and redistribute static routes into other routing protocols OSPF default after the cost , but this command to redistribute directly connected interface. invalid.

The former is used to discover the router and causes the router to send the Router. Epoch 0 Message type Area Address(es): 49.0001 SNPA: *HDLC* The GW configuration is as follows: Fa0/0 In the IPv6 specification, the aggregatable global unicast or local site address is not recommended as the next hop address. If you do this, the ICMPv6 redirect message will not work . Therefore, using the Linklocal address as the next hop may be more recommended in some cases. After all, the linklocal address is stable and long-lasting. When configuring the linklocal address as the next hop IP , you must associate the corresponding interface on the router.
