* router1-new is up and running h2. Steps * Verify / update cdist configuration * Checkout IP configuration ** Add VRRP IPs to loopback interface (will be used instead of keepalived) * Verify sysctl configuration * Rerun cdist, exclude announcing of routes * Adjust radvd configuration ** lower interval ** lower life time h2. cdist configuration Was written for Devuan/keepalived. Need to check step-by-step. * __ungleich_bgp_router: *TEMPFIX* ** contains static route announcements ** can only be used once the upstream networking is verified * __dcl_node_exporter: still makes sense ** Is debian/devuan specific, needs changes * __ungleich_ipv6_radvd --config router-$dc ** 80% done ** restart needs to be implemented * __ungleich_nftables --config router-$dc * --__dcl_router_resolvconf --search-path "$d"--: done ** no changes required * __dcl_tftp_http_pxe_bootserver ** ok, needs to be tested for alpine ** needs to be updated for ipv6 only boot ** could be moved to APUs * -require="__dcl_router_network" __dcl_router_keepalived --master-: done ** Needs to be ported to loopback + bgp ** -commented out statement for place6 routers-: done * __dcl_router_network --ipsuffix 5 ** Need to add keepalived IPs * # __dcl_nat64 --mtu 9000 h2. Networking * Update interfaces for alpine ** -place6- ** place5 h2. Implementing virtual IPs with BGP * Announce the IPv6/128 IPv4/32 address ** Or network alone is enough? * -Add Add the addresses to the loopback interface-: done interface ** all done locally on router1-new ** Needs to be put back into cdist * Add addresses for place5 h2. Firewalling h2. Change router advertisements We will have 2 active routers now with both advertising with radvd at the same time. This is part of replacing keepalived. * -Change router advertisement lifetime to 10 seconds- * -Change advertisement interval to 3..5- * Modify cdist type to restart/reload radvd on changes <pre> MinRtrAdvInterval 3; MaxRtrAdvInterval 5; AdvDefaultLifetime 10; </pre> h2. Switch configuration * Switches *might* need ipv4 bgp peering for providing virtual IPv4 address support * Don't see traffic on router1-new from upstream ** Need to verify trunk configuration on switches <pre> switch5-place6(config)#vlan 100 switch5-place6(config-vlan-100)#name netstream switch5-place6(config-vlan-100)#write Copy completed successfully. switch6-place6#configure switch6-place6(config)#vlan 100 switch6-place6(config-vlan-100)#name netstream switch6-place6(config-vlan-100)#write Copy completed successfully. </pre>
