-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 I might be wrong but isn't load balancing based on CEF which does the balancing on a hash of the Source/Destination IP, thereby it would follow only one of the routes each time as the source/destination IP hash does not change.
Bradley From: [email protected] [mailto:[email protected]] On Behalf Of Taqdir Singh Sent: 12 January 2010 15:32 To: [email protected] Subject: [OSL | CCIE_RS] Static route Selection Hi All, I have one doubt in static route selection. Please see my attached network diagram. Between R1 and R2, one is serial link and one is ethernet. If I configure R1 as ip route 2.0.0.0 255.0.0.0 se0/0 ip route 2.0.0.0 255.0.0.0 20.0.12.2 then I see traceroute to 2.2.2.2 is load balanced on both links R1(config)#do tr 2.2.2.2 Type escape sequence to abort. Tracing the route to 2.2.2.2 1 20.0.12.2 164 msec 10.0.12.2 140 msec * but If I configure on R1 as below then traceroute to 2.2.2.2 follows serial link only ip route 2.0.0.0 255.0.0.0 10.0.12.2 ip route 2.0.0.0 255.0.0.0 e1/0 R1(config)#do tr 2.2.2.2 Type escape sequence to abort. Tracing the route to 2.2.2.2 1 10.0.12.2 196 msec * 140 msec Could anyone please clear what is happening here ? - -- TAQDIR SINGH Network Engineering (+91) 991.170.9496 | (+91) 801.041.5988 -----BEGIN PGP SIGNATURE----- Version: PGP Desktop 9.12.0 (Build 1035) Charset: us-ascii wsBVAwUBS0yYb4MqcCx81E71AQjZqQf/fXzNKimmUO83PVS67lbYYa2ta/hlBi55 BfHdnhC+8TYNO1QNwEMHXMdIk07OxHsvic9uF23i8NAl/aFec8PXZvgdy5UeCsnW 6fgkqeYEM502a6gKvCI2FCermeTbpQkXHT9dMsKatoWjo7x8S5eauEmgADTZFecM 0+RCls8LF1JqeomeKcuS/ho970QnCeD1ay+rtcmqNjBSfa9oXxR5+KtpD0tcSxdy n2oyS4Kzyk4OT8n3WV1x2l8GMLmPVqr1mLnOosvxRNviow6snWMjBxY6mRWnz+D2 TX6nj72nXQqiJzxn6XO1K3Gullo7KPBzKnTM6gVOhTnvA7NVK8Uppw== =IGOh -----END PGP SIGNATURE-----
