An AS using BGP confederations, as defined in RFC 3065, separates each router in the AS into one of several confederation sub-autonomous systems (sub-autonomous systems). Peers inside the same sub-AS are considered to be confederation iBGP peers, and routers in different subautonomous systems are considered to be confederation eBGP peers. Confederations propagate routes to all routers, without a full mesh of peers inside the entire AS. To do so, confederation eBGP peer conne..
OSPF Design in Light of LSA Types
OSPF’s main design trade-offs consist of choosing links for particular areas, with the goal of speeding convergence, reducing memory and computing resources, and keeping routing tables small through route summarization. For instance, by using a larger number of areas, and the implied conversion of dense types 1 and 2 LSAs into sparser type 3 LSAs, the OSPF LSDBs can be made smaller. Also, link flaps in one area require SPF calculations only in that area, due to the partial ..
CiscoWorks Wireless LAN Solution Engine
CiscoWorks WLSE is a centralized network management system for Cisco Aironet solutions. WLSE is a key component of SWAN and consists of the following features: ■ Automatic access point configuration ■ Assisted site surveys ■ Centralized firmware updates ■ Dynamic grouping ■ VLAN configuration ■ Multiple service set identifier (SSID) support ■ Customizable thresholds ■ Fault status ■ Intrusion detection system ■ Security policy monitoring ■ Secure user in..
The Subnet Mask Support field indicates the mask of the route. If this field is 0, the subnet mask is not included for that routing entry. The Subnet Mask field in RIPV2 assists VLSM because every route that is advertised by the RIPV2 routing process carries the actual mask of the route being advertised. This is unlike version 1, in which the router assumes that all the routes with knowledge of the connected network have the same masks as the connected network. RIPV1 does not..
Just as you can configure a router to act as a DHCP server for IPv4 addresses, Cisco's IOS also includes an IPv6 DHCP server function: Router1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router1(config)#ipv6 dhcp database flash:/DHCPv6-db Router1(config)#ipv6 local pool VLAN10-pool AAAA:1::/48 64 Router1(config)#ipv6 local pool VLAN11-pool AAAA:11::/48 64 Router1(config)#ipv6 dhcp pool DHCPv6POOL Router1(config-dhcp)#prefix-delegati..
