Router Configuration Engineering Workshops
Cisco Router Configuration • Rule #1: What Would v 4 do? – Enable routing • ipv 6 unicast-routing – Configure Interfaces • ipv 6 address – Configure Routing Protocols Engineering Workshops
Cisco Configs • LAN Interface interface Ethernet 0/0 ip address 192. 168. 1. 254 255. 0 ipv 6 address 2001: 468: 123: 1: : 2/64 Engineering Workshops
Cisco Configs • Tunnel Interface interface Tunnel 1 description IPv 6 to Abilene no ip address no ip redirects no ip proxy-arp ipv 6 address 3 FFE: 3700: FF: 105: : 2/64 tunnel source ATM 2/0. 1 tunnel destination 192. 168. 193. 14 tunnel mode ipv 6 ip Engineering Workshops
Cisco Configs • ATM PVC interface ATM 2/0. 3 point-to-point description My Giga. Po. P no ip redirects no ip proxy-arp pvc My. Giga. Po. P 3/66 ubr 155000 encapsulation aal 5 snap ! ipv 6 address 2001: 468: FF: 555: : 1/64 Engineering Workshops
Cisco Configs • IGP - most sites will use RIPng for now, but IS-IS is also available. OSPFv 3 is on the way. . . ipv 6 router rip ipsix redistribute connected interface Ethernet 1/0 ipv 6 rip ipsix enable ipv 6 rip ipsix default-information orig • Static ipv 6 route <prefix> <nexthop> Engineering Workshops
Cisco Configs • BGP - added to your existing IPv 4 BGP config router bgp 64555 bgp router-id 192. 168. 2. 1 neighbor Abilene-v 6 peer-group neighbor Abilene-v 6 remote-as 11537 Engineering Workshops
Cisco Configs • BGP continued. . . address-family ipv 6 unicast neighbor Abilene-v 6 activate neighbor Abilene-v 6 soft-reconfiguration in neighbor Abilene-v 6 prefix-list to-Abilene-v 6 out neighbor 2001: 468: 555: 200: : 6 peer-group Abilene-v 6 network 2001: 468: 4 ff: : /48 aggregate-address 2001: 468: 4 ff: : /48 summary-only exit-address-family Engineering Workshops
Cisco Configs • BGP continued. . . ipv 6 route 2001: 468: 4 ff: : /48 Null 0 ! ipv 6 prefix-list to-Abilene-v 6 seq 10 permit 2001: 468: 4 ff: : /48 Engineering Workshops
Cisco Configs • Securing Console Access ipv 6 access-list V 6 VTY permit 2001: 468: 4 ff: : /48 any. . . ! line vty 0 4 ipv 6 access-class V 6 VTY in Engineering Workshops
Cisco Show Commands • • show bgp summary show ipv 6 bgp neigh <addr> routes show ipv 6 bgp neigh <addr> advertised show ipv 6 route show ipv 6 interface show ipv 6 neighbors Engineering Workshops
The Cisco Show show ipv 6 interface ! show all v 6 address etc. show bgp sum ! show summary of neighbors’ BGP state show bgp ! show all v 6 BGP-learned routes show bgp neigh [addr] routes ! what he’s sending show bgp neigh [addr] advertised ! what you’re sending show ipv 6 route ! show all v 6 routes Engineering Workshops
Juniper Router Configuration • Rule #1: What Would v 4 do? – Enable routing - already there. . . – Configure Interfaces • family inet 6 address – Configure Routing Protocols and RIBs Engineering Workshops
Juniper Configs • Interface (physical) interfaces { fe-0/1/0 { unit 0 { family inet 6 { address 2001: 468: 123: : 1/64; } } Engineering Workshops
Juniper Configs • Interface (tunnel) interfaces { ip-0/3/0 { unit 0 { tunnel { source 192. 168. 2. 2; destination 192. 168. 45. 2; } family inet 6 { mtu 1514; address 2001: 468: 123: : 1/64; } } Engineering Workshops
Juniper Configs • Router Advertisement - not enabled by default protocols { router-advertisement { interface fe-0/3/0. 0 { prefix 2001: 468: 123: : /64; } } } Engineering Workshops
Juniper Configs • Routing setup routing-options { interface-routes { rib-group { inet 6 ifrg 6; } rib inet 6. 0 { aggregate { route 2001: 468: 4 ff: : /48; } } Engineering Workshops
Juniper Configs • Routing setup continued. . . rib-groups { ifrg 6 { import-rib [ inet 6. 0 inet 6. 2 ]; } } router-id 192. 168. 2. 1 } Engineering Workshops
Juniper Configs • IGP - RIPng and IS-IS are both available protocols { ripng { group local { export redist-direct; neighbor fe-0/1/0. 0; } } } policy-options { policy-statement redist-direct { from protocol direct; then accept; } } Engineering Workshops
Juniper Configs • BGP protocols { bgp { group Abilene-v 6 { type external; family inet 6 { unicast; } export to-Abilene-v 6; peer-as 11537; neighbor 2001: 468: 555: 200: : 6; } } } Engineering Workshops
Juniper Configs • BGP continued. . . policy-options { policy-statement to-Abilene-v 6 { term accept-aggregate { from { route-filter 2001: 468: 4 ff: : /48 exact; } then accept; } term reject { then reject; } } } Engineering Workshops
Juniper Show Commands • • • show bgp summary show route advert bgp <addr> show route rece bgp <addr> show route table inet 6. 0 (terse) show interfaces show ipv 6 neighbors Engineering Workshops
