- Tunnel-broker på gammal c2621 ... http://www.velocityreviews.com/forums/t379267-2621-ssh-client-hanging.html
- IOS (tm) C2600 Software (C2600-IK9O3S3-M), Version 12.3(15), RELEASE SOFTWARE (fc3)
- System image file is "flash:c2600-ik9o3s3-mz.123-15.bin"
- Nice Slides describing IPv6 Extension headers
Tough Questions
- When implementing a 6to4 tummel, which ipv6 address is the correct translation of the ipv4 address 192.168.99.1?
- 2002:c0a8:6301::/48
- What does the command clear ipv6 ospf process accomplish?
- The OSPF database is repopulated. Then the shortest path first (SPF) algorithm is performed.
- What does the command clear ipv6 ospf accomplish?
- Clears the routing table and repopulates it after the SPF algorithm is preformed.
- What is ::/0 and ::/128
- ::/0 is default route and ::/128 is unspecified address
- What is LSA type 9 in OSPF
- Intra-area prefix LSA
OSPFv3 OSPFv2 0x2001 Router LSA 1 Router LSA 0x2002 Network LSA 2 Network LSA 0x2003 Inter-area Prefix LSA 3 Network Summary LSA 0x2004 Inter-area Router LSA 4 ASBR Summary LSA 0x4005 AS-External LSA 5 AS-External LSA 0x2006 Group Membership LSA 6 Group Membership LSA 0x2007 Type-7 LSA 7 NSSA External LSA 0x0008 Link LSA 0x2009 Intra-area Prefix LSA
- IPv6-only-node -> NAT-PT -> IPv4-only-node
IPv6 host wants to communicate with IPv4 host, what will occur- IPv6 host can NOT use DNS to find IPv4 address (rob says: it does not understand IPv4 addresses)
- CORRECT: router will determine IPv4 address
- Which two statemets are correct about 6to4 tunneling?
- Each 6to4 site revieves a /48 prefix in a 6to4 tunnel
- Prepend 0x2002 with the ipv4 address creates an IPv6 address that is used in 6to4 tunneling
- What NSAP address is a private, locally administered address?
- NOT 39.xxxx.xxxx..
- NOT 48.xxxx.xxxx...
- NOT 52.xxxx.xxxx...
- CORRECT 49.0004.30ac.0000.3090.c7df.00
- To enable BGP tunneling over an IPv4 backbone, the IPv4 address 192.168.30.1 is converted into a valid IPv6 address. Which three IPv6 addresses are acceptable formats for the IPv4 address?
- 0:0:0:0:0:0:192.168.30.1
- ::192.168.30.1
- C0A8:1E01
- What is the L2 multicast address when sending to 239.255.8.5 running on MAC 01.b2.7d.05.f1.80
- 01.00.5e.7F.08.05 (25 bits , not 24 Rob thinks...)
- Which of the following is a GRE tunnel characteristic?
- GRE tunnels can run through IPsec tunnels
- FALSE GRE impose more CPU overhead then IPsec on VPN gateways
- FALSE GRE tunnels does not support IPv6
- FALSE? GRE consists of two sub-protocols: ESP and AH
- exhibit of "show ipv6 ospf interfaces"
- TRICK this commands does NOT show global IPv6 addresses
- CORRECT OSPFv3 uses Link-local addresses to establish neighbor adjacencies
- For IPv6, what term or phrase best describes a type 9 LSA on OSPF?
- Intra-Area prefix LSA
- What is the benefit of deploying IPv6 in a campus network using dual stack mode?
- IPv4 and IPv6 run alongside one another and have no dependency on each other to function
- FALSE: IPv6 and IPv4 share network resources
- Which Three are characteristics of IPv6
- An IPv6 address is 128 bits long
- An IPv6 header contains the next header field (rob says: Shared with Protocol Field)
- An IPv6 router send RA messages
- You have been tasked with setting up OSPF on an existing Cisco router using IPv6. Which command enables OSPF for IPv6 on a router?
- ipv6 router ospf process-id
