VLan 30 und 40 sind activ. Warum:? Weil auf DSL2 die größte IP-Adresse ist? Beide DSLs haben die gleiche Prio jedoch unterschiedlihe activ states. Kann mir das wer erklären.???? Quote
Otaku19 33 Posted February 4, 2008 Report Posted February 4, 2008 hm, hab ich Tomaten auf den Augen, ich seh kurz zusammengefasst: DLS1:physikalische IP immer 172.16.VID.3 DLS2:physikalische IP immer 172.16.VID.4 virtuelle immer 172.16.VID.1,priority immer gleich. meine Tipps wären: wer zuerst kommt mahlt zuerst Fehler in der Aufgabenstellung/SIM und es sollten unterschiedliche prios da sein. Die Konfig so wie angegeben macht mir Kopfzerbrechen Zum überfliegen wäre es einfacher wenn man nur die Config teile hätte Quote
cky 10 Posted February 11, 2008 Report Posted February 11, 2008 Moin, Frage: Warum sind nicht alle Vlans vom DLS2 im HSRP Activ Mode? VLan 30 und 40 sind activ. Warum:? Weil auf DSL2 die größte IP-Adresse ist? So wie ich die Konfig überfliege, sollten auf'm DSL2 alle Vlans im "active" sein. Bei gleicher Priority, wird der Active, der die höchste IP in dem VLAN hat. Allerdings, im show vom DSL2 steht folgendes: DLS2# show standbyVlan1 - Group 1 State is Standby 3 state changes, last state change 00:02:33 Virtual IP address is 172.16.1.1 Active virtual MAC address is 0000.0c07.ac01 Local virtual MAC address is 0000.0c07.ac01 (v1 default) Hello time 3 sec, hold time 10 sec Next hello sent in 2.950 secs Preemption enabled Active router is 172.16.1.3, priority 150 (expires in 8.960 sec) Standby router is local Priority 100 (default 100) IP redundancy name is "hsrp-Vl1-1" (default) Sicher das Du auch wirklich Priority 150 eingeben hast? So wie ich das sehe, ist es nicht so, da er die Default-Priotity 100 nimmt. Thomas Quote
Franz2 10 Posted February 11, 2008 Report Posted February 11, 2008 Am besten du setzt auf dem Switch der active sein soll die Priority auf 110. Die priorty auf den Switch der Standby sein soll lässt du auf den default Wert (100). Dann sieht man gleich wer active sein soll. lg Franz Quote
