Symptom: EIGRP BW is different that the one on the Multilink interface after a reload. Router#show ppp multi int multilink205 Multilink205 Bundle name: ROUTER2 Remote Endpoint Discriminator:  ROUTER2 Local Endpoint Discriminator:  ROUTER Bundle up for 00:23:48, total bandwidth 7936, load 1/255 <<<<<<<<<<<<<<<<<< Receive buffer limit 48000 bytes, frag timeout 1000 ms 0/0 fragments/bytes in reassembly list 0 lost fragments, 2 reordered 0/0 discarded fragments/bytes, 0 lost received 0x13F received sequence, 0x184 sent sequence Member links: 4 active, 0 inactive (max 16, min not set) Se0/0/0:0, since 00:23:48 Se1/3/5:0, since 00:23:47 Se1/3/7:0, since 00:23:47 Se1/3/6:0, since 00:23:45 ROUTER#sh ip eigrp topology 10.111.4.242 255.255.255.255 EIGRP-IPv4 Topology Entry for AS(124)/ID(10.111.5.8) for 10.111.4.242/32 State is Passive, Query origin flag is 1, 1 Successor(s), FD is 942080 Descriptor Blocks: 0.0.0.0, from Rstatic, Send flag is 0x0 Composite metric is (942080/0), route is Internal Vector metric: Minimum bandwidth is 5952 Kbit <<<<<<<<<<<<<<<<<< Total delay is 20000 microseconds Reliability is 255/255 Load is 1/255 Minimum MTU is 1500 Hop count is 0 Originating router is 10.111.5.8 Conditions: EIGRP route known via a Multilink. As several links associated with Multilink come up at different time, Final BW reported by EIGRP for static routes with nexthop as Multilink are seen with bandwidth lesser than actual.
