5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide interface. T A flag appended to an IPv6 route to indicate that it is an ECMP route, but only one of its next hops has been installed in the forwarding table. The forwarding table may limit the number of ECMP routes or the number of ECMP groups. When an ECMP route cannot be installed because such a limit is reached, the route is installed with a single next hop. Such truncated routes are identified by a T after the interface name. In order to control the traffic destined for a particular network administratively and prevent the traffic from being forwarded through a given router, a static reject route can be configured on the router. The traffic would then be discarded and an ICMP destination unreachable message would be sent back to the source. This approach is typically utilized to prevent routing loops. The reject route that is added in the recovery time object (RTO) will be OSPF Inter-Area types. Reject routes (REJECT route types installed by any protocol) are not redistributed by OSPF and are supported in both OSPFv2 and OSPFv3. 8-45 show ipv6 route ecmp groups Reports all the current ECMP groups included in the IPv6 routing table, where an ECMP group consists of a set of two or more next hops that are used in one or more routes. Such groups are numbered in an arbitrary manner from 1 to n. The output for the command indicates both the number of next hops in the group as well as the number of routes that utilize the set of next hops. The output also includes the lPv6 address and the outgoing interface for each next hop in each group. show ipv6 route ecmp-groups Parameters None Default The default is None. Command Mode Privileged EXEC Example The following is an example of the CLI display output for the command. (router)#show ipv6 route ecmp-groups ECMP Group 1 with 2 next hops (used by 1 route) 2001:DB8:1::1 on interface 2/1 2001:DB8:2::14 on interface 2/2 ECMP Group 2 with 3 next hops (used by 1 route) 2001:DB8:4::15 on interface 2/32 2001:DB8:7::12 on interface 2/33 2001:DB8:9::45 on interface 2/34 838
