Image ! The allocated portion of the entire IPv6 space: Sending 1, 1500-byte ICMP Echos to 2034::4, timeout is 2 seconds: Router(config-if)#ipv6 adress 2002::/64 eui-64 !! Also configured with an IPv6 address and populated with EUI-64 To control, the most simple and convenient. Ipv6 enable Mpls label range 400 499 mpls ldp router-id Loopback0 OR1 configuration The maximum hop count is still 15 hops Ip route 0.0.0.0 0.0.0.0 192.168.123.1 Router ospf1 Router(config-rtr)# timers update expire holddown garbage-collect Prefix readdressing But on R1 : !! ipv6 routing, all traffic to the IPv6 network is thrown into the tunnel Here to add a sentence, since attention to traffic, we must pay attention to the round trip of traffic, in general, we want 1.1.1.0 access 3.3.3.0 traffic to go ADC , then round-trip traffic generally requires a consistent path. That 3.3.3.0 to 1.1.1.0 data to a CDA , so to further D on the update to the C of 1.1.1.0 route of metric plus 1 jump. Interface FastEthernet0/0 ipv6 enable Ipv6 unicast-routing EIGRP 's passive-interface neither sends nor receives routing updates, nor does it send HELLO packets. Address-family ipv4 Image The configuration of R2 is as follows: The PMTU discovery protocol is defined in RFC1981 . IPv6 PMUTD uses ICMPv6 Type 2 messages. The typical process is as follows: Policy-based routing is more powerful and flexible than traditional routing. It allows network managers to select forwarding paths based on destination addresses and packet types, packet sizes,ccna security dumps pdf, applications, or IP source addresses. Ipv6 nd ra-interval On R1 , only the summary route 32.0/21 is filtered, and all the detailed routes are released. If a standard ACL is used to match the route, how to write it? Ipv6 address 2001:5555::5/128 interface FastEthernet0/0 2001:1111:: 0000:5efe:0202.0202 /64 , so the prefix of IPv4 is 2001:1111::/64 , this prefix will pass through the tunnel later. ...... Suitable for infrequent IPv6 node connection needs. The IPv4 compatible tunnel is implemented through the tunnel virtual interface. If the encapsulation mode of a tunnel interface is an IPv4- compatible tunnel, you only need to configure the source address of the tunnel. The destination address is the destination address of the IPv6 packet when the packet is forwarded . Acquired. The destination address of an IPv6 packet forwarded from an IPv4- compatible tunnel must be an IPv4- compatible IPv6 address. The destination address of the tunnel is the last 32 bits of the IPv4- compatible address . If the destination address of an IPv6 packet is not an IPv4- compatible address, it cannot be forwarded from the IPv4- compatible tunnel.
